Shaker used in the mining industry characteristics

Vibrating screen is widely used in mining, ceramics , coal, chemical and other industries, many models of vibrating screen for

Meet the needs of different industries , vibrating screen appearance and structure is somewhat different , in which linear vibrating screen and

Circular vibrating screen is two good dewatering screen representatives of the two vibrating screen customers are quite satisfied . Well, according to vibration

The working principle and structure of the sieve shaker can be divided ;
1 , heavy vibrating screen, vibrating screen that is in the mining industry , mining vibrating sieve shaker as a heavy-duty , in

Production line is also a relatively common screening equipment . But such a shaker or a certain defect , when the

However , there are also many materials vibrating screen design with a certain relationship , in short, this style of production and screening effect shaker relatively

Low, and the work of such vibrating screen area is relatively small , vibrating screen mesh material likely to be blocked. But this earthquake

Moving Screen is also very obvious advantages , this shaker working process, his good power balance , screening process

In low speed shaker and the work is relatively stable . This is a heavy duty vibrating screen a big advantage .
2 , circular vibrating screen . Circular vibrating screen is mainly used in the production pipeline , right before the broken material is sieved

Circular vibrating screen is a major role in the mining industry to use it more of a screening device. The disadvantage is that circular vibrating screen

Screening and production efficiency is low , the advantage of not consume power , shaker manufacturing process results simple and convenient, and can be

Discharged directly to the screen surface materials .

How to effectively solve the vibration sieve static problems in the process of

In the process of using vibrating screen , vibrating screen users often encounter the phenomenon of static electricity , which can cause static electricity

Is varied , as some materials are themselves contain static and vibrating screens and screen material during friction

Rub will produce static electricity, if we crusher manufacturer do not try to solve these static, then the shaker is not working materials Jietuan

Easily through networks, can also cause harm stone screening machine to humans . So for a project at work shaker static how we should

What do we solve it ?

We can access the sieve shaker bottom line, so that the current export , you can also join in the materials before the screening anti- static

Power agent. Otherwise, it can increase the strength and efficiency of the work shaker .

The working principle of vibration sieve

Vibration sieve is made ​​by the vertical vibration motor vibration source , since the upper and lower ends of the weight attached to the motor shaft at both ends , the rotary

motion of the motor into a vertical,coal vibrating screen  horizontal , and three dimensional power inclined , by changing the upper and lower ends weight of the phase angle , can change the

direction of rotation of raw materials

Processing of raw materials to meet oscillating screen the needs .
 The technical requirements of vibration sieve
Vibration sieve shaker as one , there are many requirements concern:
1 rotary vibration sieve requirements TIG welding parts welding and showing scaly form
2 : vibrating body portion , vibrator vibration sieve plate requires more than 5mm , the motor plate requires 12mm, to avoid vibrations in the long process of cracking
3 : rotary vibration sieve spout part , requiring both inside and outside polish.

In choosing a shaker device is to be given to those

Customers choose shaker device is what should be considered :
    Shaker customers ready to buy the equipment when not quite understand how to choose the client device , the following details about . Select vibrating screen equipment in

general to consider a space-saving apron feeder drive power to be small. At the same time to be able to guarantee rotation and pulsation amplitude of movement to be small, vibration

frequency

Rate should reach three thousand times per minute , or a combination of centrifugal force and amplitude -frequency vibration and other factors are likely to affect the normal

operation of any shaker . In addition , sand vibrating screen the need to have a correct combination of the direction of slope and rotation mechanism, which is essential for display . Typically

, Shaker requires a large opening , large amplitude display. If too little investment , then the material may be wedge-shaped openings , etc. , or clogs . Increase investment in

the future , need to know how to prevent clogging because blockage is unnecessary and will increase the daily wear and bearing

And lower screening efficiency. Material per unit time to be increased rate curve through the entire screen, so there material at a faster rate while the lathe by a thin high

efficiency needed for screening. When the material too fast and cause the material to ribbons by the breakdown when the material reaches

Screen appears when opening the cloth maximum tilt angle . At this time a large number of high-quality material through the screen too quickly , resulting in poor efficiency .

When an existing screen fails, if the screen structure is also suitable for new applications , then should be timely checked and consultation

Ask vendors to see if there is a need to modify the place . Operators can also pass the following information provided by suppliers to get a good shaker, the highest tons per

hour through the filter , including any cyclic loading or any sudden increase in feed rate . Particle through a complete

Analysis or analysis of the material for screening , if conditions allow , the best estimate analysis method used . The type of material and the weight of the probability of

failure per cubic meter . Each sieve expected fracture. Material carried by the surface of the water filter , if it is required to damp

To add a certain amount of water or of dried material . Special operating requirements or conditions , such as temperature, wear, corrosion or with other physical properties of

materials, efficiency and product requirements, determine filter surface or installation problems because it will directly affect the screen size

Inch screen real choices, and the ability to use . General Type: vibrating screen can be divided into two categories : one for mechanical vibratory shaker, the other for power

by the vibrating shaker .

Vibration sieve sieve correct knowledge points selection method

Vibration sieve sieve correct selection method [
Vibration sieve ( three million vibration sieve ) installed on top of the screen according to the different materials , the material is also different , however, with stainless

steel braid more, and wear and coal screening machine longer life.
Shaker screens installed on top , is screening the material according to the customer to select the suitable sieve size and material . Sieve size the same, but wire diameter is

different, there is a small rough . How oscillating screen to choose the right screen machine how to install , refer to the following introduction :
1 If a relatively high or sieve size larger proportion of the screening material , you need to add a layer of the bottom of the screen mesh is more suitable for the trawl , so

play a supporting role , thereby reducing the material on the sieve net pressure , but also can prolong the life of the screen .
2 wire sieve shaker to choose wire by a relatively thick stainless steel mesh , wear long service life. Shaker screen when the crop length than the grid length 50-70mm, width

and screen frame consistent with the line.
3 After installing everything , put some material on the screening machine for testing and screening situation , start vibrating screen where the material is fed forward evenly

, classification accuracy and no mixing phenomenon , can be used normally ; Conversely , if there is material poly heap to one side or the other phenomena , we need to adjust

the screen

Network uniformity and flatness ; if mixing phenomenon , you should check whether the sealing mesh compression .
4 In the bouncing ball when put clean network , taking into account the material and screening mesh difficulty appropriate to add bouncing ball , not added much like the

vibrating screen mesh tension will directly affect the efficiency of screening , be sure to tighten the screen at the same time re- installation.
5 grid on demand installed into sieve box , pay attention to grow into the mesh to the corresponding end of the line discharge mouth to avoid mixing phenomenon . The

installation plate , to maintain a high flatness, then a relatively strong elasticity foam lined with a uniform locking seal to avoid mixing is

Screen directly affect the service life of the key.

Vibrating machinery manufacturers how to increase website conversion rate

Vibration equipment online turnover rate need to look at several aspects: an accurate description of the display of goods and beautiful goods → → → customer to convince

customers to buy the products
An accurate description of the Mobile crushing plant value of goods
Use short text , high strength characteristics of the broad commodity . The viewer's time is limited , he will not spend too much time to see the introduction of your product

information will only hurried sweep . So we want to say a brief introduction to the beginning . In this regard

It is best to take the time and effort to do it.
Two , beautiful display of goods
In addition to your text description, mobile screening plant viewers will be interested in is the picture. Colorful pictures to attract his attention, which would leave him impression. He was not

specific on the network can be physical , it is only through text descriptions with pictures to introduce the show , the two parties

Faces are mutually complementary .
Third, try to convince customers
Allow customers to take the initiative to put the money to pay out , it takes a certain skill . I do not know how many owners have learned to sell or a sales job done , but not

everyone is try to lower prices of wool will fight the main thing is to see your product or your sales marketing strategy is effective

, And often customers buy a lot of stuff on the Internet is not necessary because there is a compulsive online shopping psychology, people generally have this mentality often on

the Internet to see some things very cheap to buy , they will be very major tourists, as far as possible in the process of persuasion standing right

Side of the angle.
Fourth, the customer to buy the products

When the customer bought , he 's worth more than you are new to follow him when to be larger , you do an effective customer care ? Whether you recall the customer's other

demands , for the goods sold there do secondary visit ? these are the need for a large number of return visits . Sale

After , there is the late maintained . Only the combination of all links to be able to generate greater efficiency.

Vibrating sieve accuracy of less than how to solve

   Improve screening accuracy oscillating screen adapt material grading requirements. Better complete screening task is normal operation shaker .
Main performance and solution:
1 mesh sieve clogging ( to increase the anti-clogging device )
2 dropped into shaker material moisture sieving machine is too large ( viscosity, appropriate after drying into shaker )
3 vibrating sieve surface feeding inequality ( increased material shunt )
4 shaker screen surface material layer is too thick ( add material shunt control feeding amount )
5 Pull the screen is not tight , too loose drive belt
Workaround:
1 often to relieve the load and clear light shaker sieve shaker
(2) changing the angle of the screen box
3 . Mediation shaker feeding amount
4 tension screens, narrow belt
Sieve shaker is also an important part mesh size , mesh material , the size of the vibration force will affect the accuracy.

How reliable vibration motor mounting

, easy installation , no transmission vibrating screen manufacturers components , and can be part of the vibration and many other advantages , more and more applications in various industries extensive. The

general structure of the vibration motor shown in Figure 1 ,

That allogeneic seat shell with shell seat one. Shell seat variant ( Fig. 1a) , respectively foot supporting surface fused with two end caps , and its manufacture is more

convenient , there are still many manufacturers vibrating screen supplier use , but its drawback is two bottom foot is processed twice . Since the existence of assembly errors , and some foot

Surface can not be guaranteed in a unified horizontal plane , so that the vibration motor work, a few foot bolts of the force will be uneven. The vibration motor excitation

force almost all these bolts passing through , so that a larger force on the bolt is easy to damage , in turn cause other spiro

Bolt damage burning motor . And Fig 1b, one of the seat shell of the vibration motor because all of the foot on the housing bottom , easy processing time , thus ensures that the

bottom level of the foot , eliminating the above-mentioned problems, the vibration motor life can be guaranteed .

Vibration sieve FAQs processing

Vibration sieve in the course of blocking network phenomenon sometimes appear , then what causes it ? Sometimes it may be our material viscosity is too large, so this case we

can not put too much time coal screening machine.
Most of the main approach is as follows:
1, when the fine-grained material , clay content of more, and sieve size is small, the water on the screen plugging it play a decisive role .
2 , when the material is greater than 5% moisture , if the material for drying unconditionally , response sieve , sieve for the targeted selection.
3 , when the water is greater than 8%, should be used wet sieving .
4, flaky particles more material , you need to change the broken material crushing methods and different ways with the granularity of the process .
Reasonable to reduce the tension adjustment Linear vibrating screen mesh clogging is an effective method , the tension of the screen reasonable support beam with a slight secondary vibration ,

thus effectively reducing the occurrence of clogging , practice, Constant tension of the tensioning hooks made ​​of bodies, namely the tension bolt

On the installation of springs.
The importance of safe operation as a non -standard equipment shaker vibration equipment for most users, the shaker may all devices in the user hardly a major equipment ;

however shaker failure frequency is higher than the traditional power machinery products, The reason is vibrating device itself

Is a kind of vibration destructive conduct scientific use of a product. Equipment for conventional mechanical vibrations , it means that the occurrence of failure sign , and by

vibrating the vibration device is precisely the work required to complete one purpose and requirements of a product. Although vibration industries

Is committed , anti- vibration device itself destructive optimized structure design and research, but still vibrating equipment failures occur frequently . And the vibration

sieve is often arranged in the production process the user 's throat , once shaker fails, will cause the linkage to stop the entire production system

Car , giving users a significant loss of production . On mining, coal, metallurgy enterprises, such as a sudden stop repair one day , then at least ten direct production

efficiency loss of tens of thousands , as many as hundreds of thousands or even millions of dollars . To avoid this phenomenon, the user only keep abreast

Shaker operating conditions , to discover hidden maintenance arrangements well in advance .

Vibration sieve material

With the growing popularity of vibration sieve , vibration sieve for different purposes , and now vibration sieve materials have vibrating screen supplier different changed. We generally see generally

have three of material:
1, ordinary carbon steel :
This material so that we often see . Used for non-corrosive materials , powder and other materials. Because the material is easy to rust when wet , so the working environment

must be dry.
2,304 stainless steel :
This material vibration screen is we often see one. Used for corrosive and environmental humid environment .
3 , plastic steel :
This material vibration sieve relatively rare , usually only for special customer requirements custom-made .

The working principle of vibrating screen

  Shaker work, two vibration motors synchronized reverse rotation of the exciter excitation force generated reverse , forcing mesh sieve to make longitudinal movement of the

drive to make the material
Subject to periodic excitation force and Vibration feeder thrown forward a range, thus completing the materials screening operations . Suitable for screening sand and gravel quarry , but also

for coal preparation, mineral processing , building materials, electricity and chemical
Industry for product classification purposes . Shaker working part fixed and depend on the material slide along the face leaving materials are sieved . Fixed grizzly is more of

a concentrator applications
Generally used for rough broken or banana screen crushed before the pre-screening process . It is simple in structure , easy to manufacture . Not consume power , you can unload the ore

directly to the screen surface . The main disadvantage is the low productivity , screen
Of low efficiency, generally only 50-60%.

How to solve the problem of vibrating screen bearing heating

          Circular vibrating screen working principle is to use a vibrating screening equipment , screening material because of its large capacity, high efficiency, simple

structure , stable and reliable , and Vibrating feeder therefore the wider application of sand making production line . In addition to the main components shaker vibration under

Beyond the number necessary to move the motor to the bearing , the bearing will have a direct impact on the quality of vibrating screen , vibrating screen bearings in use , the

temperature rise is too large, easy to make the vibrating screen bearings produce damage , affecting the use of vibrating screen . Excessive heat vibrating screen bearings are

mainly the following reasons:
1 , lubrication unreasonable , Pan feeder , or too much or too little fuel .
2 , vibrating screen bearing structure design is unreasonable .
3 , the bearing manufacturer is qualified.
4, the lubrication system is a problem .
5 , if it is a new screen, it must be process issues, circular vibrating screen sieve if it is old , stiffness , infrastructure and so on.
6 , the bearing with the bearing with a reasonable selection, fever and affect the bearing life.
7 , cement vibrating screen bearings precision problem, because domestic processing precision is not enough , so the use of three groups of large clearance bearings, these

bearings are used at the expense of increasing the noise .
8 , the focus error is too large sieve .
9 , vibrating screen bearing clearance to choose appropriate.
10 , bearing installation is correct or not , tolerances reasonable or not, electromagnetic shaker is critical fever .
Circular vibrating screen work process is to rely on power running , never load low speed and slowly increase to the conditions set rated operation . So clients commissioning

circular vibrating screen items must be checked as whether group in abnormal noise , bearing temperature shift , catch and release lubricant such as discoloration

And so on. Check the bearing temperature shaker general appearance from the housing speculation seen. But the use of the hole , the direct measurement of the bearing outer ring

temperature , more accurate. Start of operation of the bearing temperature rises gradually , without exception , typically 1 to 2 hours after stabilization . If the installation

due to bad bearings or bearing temperature

Will soar . The case of high-speed rotation , the bearing lubrication method of choice is the cause of the error .

Trommel impeller assembly is how to achieve the purpose of screening

   Trommel operation can be accurately carried out mainly by trommel impeller means , the impeller assembly is mounted on the upper end of the spindle shaft assembly head, then use the tapered sleeve and the coupling from the transmit button reach the purpose , the material from the upper part of the impeller feeder enter the high-speed rotation of the impeller center , leaves

Wheel center fabric cone evenly distribute the material to the various emission flow impeller , centrifugal impeller rotates with the rotation of the material , the material speed impeller flow channel outlet flow from the transmitter , there is an acceleration of the material to be ejected out of the whirl chamber screening equipment lining material within the natural occurrence of strong

Impact of the collision , the transmitter channel outlet streams have block protection equipment wear , and easy to replace the impeller cone hat and wear on the block has diverted material , indecent channel plate , while protecting the impeller without material impact wear . However, during the operation should be noted that the nature of the feed shall comply with the provisions of

Feeding value , to ensure continuous and uniform feeding , stop feeding stopped before , it will be very easy to wear impeller body .
   For the material in the jet impeller in motion , but if the improper operation or maintenance can cause damage to the impeller , the impeller friction material is easy to scour role in the operation of the production of scientific and reasonable attention to be able to avoid the friction material on the impeller assembly . Impeller cavity flow conductance in Screening machine

Material , change the direction of movement of materials falling protect the screening chamber is damaged friction material , extending the life of the equipment . While increasing the momentum of the material , the ability to improve the impact screening .
    Trommel features:
1 unique Liu riveting technology, increase body strength and toughness, reduce machine resonance .
   (2) The new screening trommel way to meet a variety of needs of different materials screening
   3 double pump design, bearing bit heated , a new impeller design .
   4 hydraulic maintenance starting arm , greatly reducing maintenance costs.
   5 screening equipment imported bearings , stable

Sieve causes blockage

Shaker during normal operation, all the characteristics of the material , the material will produce a variety of different shapes form a mesh plug. Sieve clogging the main reasons the following:
    1 contains a large number of particles near the separation point ;
    Two materials with higher water content ;
    3 for spherical particles or mesh material with multiple points of contact ;
    4 can be electrostatically ;
    5 material has a fibrous material ;
    6 more flaky particles ;
    7 wire mesh weaving through thick ;
    8 thick rubber mesh sieve , etc. , hole shape design is unreasonable, did not reach the small great , leaving the particles stuck.
    Because of the need banana screen material particles are mostly irregular , so blocking reasons are varied . To effectively prevent clogging shaker should be reason for blocking the sieve measures . When fine-grained material , clay content of more, and sieve size than

Hours, clogging of water on the screen to play a decisive role. When the material is greater than 5% moisture , if the material is dried unconditionally , coping sieve , sieve for targeted selection. When the moisture content greater than 8%, should be used wet sieving . More material on the tabular grains , you need to

Change material crushing crushing manner and different ways with the granularity of the process . Reasonable to reduce the tension adjustment screen mesh clogging is an effective method , the tension of the screen machinery reasonable support beam with a slight secondary vibration , thus effectively reducing the occurrence of clogging of the specific approach

Yes, the tensioning hooks made ??of Constant tension mechanism , namely the tension bolts to install springs.

Cause weighfeeder factors of error

     Governor weighfeeder by the scale body and a controller , the controller accepts the scene scale body load pressure sensor signal and speed sensor speed signal processing,

in actual use , the Crusher machine speed signal can generally reflect the actual scale body speed , low failure rate .

Therefore, the feeder , the measurement accuracy depends on the scale body load signal accuracy . Silo material level , the belt is running friction material humidity,

temperature and belt tension have directly or indirectly affect the size and direction of the belt Mobile crushing plant tension variations , resulting in the actual load

Away from the calibration load , directly affecting feeder metering accuracy .
    More varieties of feed ingredients in the case that the number of over 12 silos , even when adjusted feeder model , speed, it is difficult to control in 6min completed

within the ingredients, so to consider configure two batching scales . Two scales simultaneously ingredients, aniseed into a large scale, small material into the small

Scale, not only can greatly shorten the batching time , but also improve batching accuracy , help to improve feed quality and yield , reduce energy consumption. Weighfeeder

ensure accurate dosing , batching shorten the time .

On feeder misconceptions which

Misconceptions one : buy a feeder until the feeder should be some kind of test
      Test is to assess the characteristics of the feeder and the overall level of the seller is an effective way . But not just screen machinery any test can be carried out . Feeder test must

be based on your specific goals write a written plan, and should be as close to the actual situation of production conditions

Manner. Tests should be produced using the same materials , and transportation of materials in the same way . Feeders should be assessed in a number of performance when feeding

, feeder runtime might beat body surface to screening equipment detect unplanned disturbances feeder operation. Most

The feeding problems and multiple feed , and therefore the test should also simulate multiple feed feeding system . Should understand the manufacturer's device settings

experience, such as : feed several times per hour , or how much material level inside the hopper feed starts again . In addition, you should evaluate how long interval

Time to clean up the feeder . Requirements of certain pigments and additives and hopper feeders with a special plastic or highly polished steel, in order to clean up .
Misconceptions two : Feeders it can be mounted in any position extruder
       When installing the feeder to observe equipment operation environment. Vibration must be minimized , into the hopper and feeder vent line ( to prevent system blocking )

must not touch the measurement scales . If the device is surrounded by a lot of people at the event , then the feeder while driving may be affected by

To impact or falling objects on it, this time must understand measurement scale durability and replace damaged measurement scale required fees. Some scales are expensive and

difficult to buy.
Misconceptions three : Decide feeder control system engineers , rather than operatives
      Instrumentation control engineers and process engineers responsible for feeder control system selection and planning , and operatives must be involved in the detailed

design of the control system . Engineers often want to control the system with all alarm bells . Speaking from the truth this is a good idea , but the actual operation

Workers prefer the display on the control panel clear logic . Should therefore carefully consider the level of protection screen ( usually there are three levels of protection :

operator, equipment maintenance and engineering ) , or your feeding system may take a long driving time , because its control system

Difficult to debug .
Misconceptions four : weightlessness compensation vibratory feeder is too complicated, is not accurate enough
       Updated measurement scales electronic components and better logical calculus makes feeder with screw feeder or belt feeder as accurate . For fragile , brittle products, (

such as chopped glass fiber ) , vibration hopper , sometimes combined with a low-speed rotation of the screw, will be co-

Appropriate choice. 22 test proved vibrating feeder to 330 ~ 760lb / h speed filling pieces of glass for the production of slabs of glass containing 35% of nylon 66 , the

accuracy rate of 0.015% .
Misconceptions five : Only weightlessness compensation feeder supplying the liquid material can be accurately
      Liquid and solid except that the density of the liquid is kept constant at a certain temperature , its mobility hardly changed . A variable capacity pump almost to the

accuracy of ± 1% viscosity 0.5cp ~ 100000cp send any liquid , piston or diaphragm in the pumped liquid

Between 0.5cp ~ 100cp , and the gear pump pumping high viscosity liquids 100000cp . If you want to monitor the liquid feed rate , you can use a Coriolis meter or install a silo

integration into measurement scales . The former measure the fluid interference , which indicates real progress

Feed rate and feed rate exceeded the target range alarm . However, the feedback loop fluid flow control problems are usually caused by problems than it solves more than .
Misconceptions six : Feeders brand than the local agency is more important
      Can not be ignored by the seller 's agent network to provide reliable technical support. To minimize downtime , you must have a good local agent , he can be your need to

provide feeder manufacturer. Most feeder equipment manufacturers and sells a variety of common

Equipment dealers cooperation . If your equipment dealer tells you his home phone number , and when you need help , he will work with the manufacturer's headquarters is well

connected , then you should continue to work with him . Additionally, this agent should also have adequate professional skills,

When your maintenance staff needs help, he can go to the plant site to help you solve the problem.
Misconceptions seven : hopper feeders than side feed feeder money
      Typical side feed feeder hopper solids than the average multi- feeder several advantages , including durable structure , relatively high torque screw , screw and fully

engaged to transmit torque metal gear rather than nylon gears. When the hopper feeder is used as a side feed feeder

When running just three to four days will be damaged . Therefore, if the feeder vendors said his hopper feeder can be used for side feed feeder, you should ask him to issue a

feeder performance and service life of a written guarantee .
Misconceptions eight : volumetric feeder and feeder loss compensation accuracy can not be compared
      A match with the material volumetric feeder can have the same weight feeder performance , even more than the weight of mismatched feeder better performance. Loss

compensation only control and testing a feeder mechanism , if the feeder can continuously the material from

Feed hopper to the conveying screw or belt , then weight loss compensation can not overcome the feeder design flaws. Each weight loss should be compensated feeder capacity can

run to track the actual materials over time to lose weight . When evaluating the different feeding systems

, If feeder with screw feeder , in addition to weight loss compensation control to reduce system instability , but also should be examined under way in the volume of each feeder

accuracy to determine its inherent accuracy. Field control device performance can be improved to a certain extent , but

The design error was in need of rehabilitation equipment, and even need to replace another type feeder .
Misconceptions nine : If the display indicates that the feeder feeder was running accuracy of ± 1%, then everything is normal
      It should be understood feeder feed rate How to calculate . The rate of the display period of time within the hopper , the average weight loss . The longer the interval ,

the displayed speed value, the more able to hide any short-term fluctuations. When the feeder to 600rpm running, even though the number of

According to the collector ignores the short-term fluctuations , but you can not ignore this.
       Feeders determine whether the normal operation of the simplest way is to observe the drive command . Show driving directions screw feeder motor speed or belt feeder belt

speed. If the driver instructions fluctuations ± 5%, while the display shows the feeder feed rate of ± 1%,

Then the feed rate of the logical calculus will hide the short-term fluctuations.

Feeder in the crushing production line should pay attention to the problems

Vibrating feeder is widely used in metallurgy , mineral processing , building materials , chemicals, abrasive and other industries crushing, screening , you can put granular

bulk materials from silos timed , evenly and continuously into the affected device to go to prevent the affected device because of uneven Pan feeder produced crash phenomenon ,

Prolong the life of the crusher device .
Installation choices :
a. horizontal installation , uniform and stable material for general feeding situation prevents material gravity ;
b. downward 10 °, applicable to the general case of continuous Feeding equipment of materials ;
c. downward 15 °, for viscous or high moisture material continuous feeding situation.
Precautions before and after running :
All bolts should be tightened before running again , especially the vibration motor bolts , 3-5 hours of continuous operation should be re- tightened once ; run two vibrating

motors must reverse rotation. If the current is unstable or that there is no noise was very loud , they should immediately stop treatment .
Feeder should be how to maintain
First, due to the vibration of the motor current and motor surface temperature requirements before and after amplitude uniform, do not shake swing around , so always check the

amplitude of the vibration motor , such as abnormal situation should be shut down immediately ;
Second, the motor bearing maintenance is also very important. Motor bearings crushing production line is the feeder nozzle of key equipment, generally once every two months

filling oil , hot season once every month to raise oil . Every six months to be re- motor overhaul once inside

Ministry bearings should be replaced.

Screw feeder Detailed structure and working principle

Screw feeder to go through the material weight by weighing bridge for testing to determine the weight of the material on the tape , mounted in the tail of the digital speed

sensor , continuous measurement of the running speed of the belt weigh feeder . The speed sensor pulse output proportional to the speed of the feeder , weight signal

And velocity signals together into Vibrating feeder controller, a microprocessor for processing, generating and displaying the cumulative amount / instantaneous flow . The flow rate is

compared with the set flow rate , controlled by the output signal of the inverter control instrumentation change the drive speed of the feeder , the feeder on the matter

Feed flow rate changes, and keep the set close to the feed flow , enabling dosing .
Feeder works
Feeder using the vibrator centrifugal force generated by rotation of the eccentric block , the screening hand, the movable portion vibrator forcibly make a continuous circle or

approximately circular movement. Material is in the car with the sieve screen surface inclined to make continuous throwing motion , the material evenly and continuously feed the

mouth to the subject

.
When the feeder base plate together with the forward movement of the material , the material inside the silo fill the body followed by a space . When backward movement of the

base plate , the base material can not be on the back and along the unloading blocked , to achieve the feed . Change Backplane movement amplitude, frequency and height of the

material gate

Adjustable feeding amount . Feeding amount is generally 40 tons / hour or less. Such feeder suitable for small and medium- size materials , mainly two kinds of tilting and

trough . Pendulum feeder floor is curved , hinged on the body , the work floor swing. Feeder trough bottom is flat, for the work

Reciprocating motion.

Crusher industry competition to promote technological innovation

China 's automation technology rather late, most of the development process in order to rely on foreign advanced technology , many customers accustomed to big brand products , no longer willing to try domestic brands of crushers products. Like a vicious circle like shackles restricting Chinese technology development

, Making the crusher industrial technology capability of independent innovation is weak . crushing equipment innovation itself is a culture , especially when the independent innovation has become the main thrust of an industry , the industry will have a continuous power.

Crusher industry competition is the culture of competition , innovation around one of the most critical issue is the respect for knowledge , respect for talent and intellectual respect. Crushing machine industry in our country on the road of independent innovation made crusher manufacturer many useful contributions , while adhering to

Own brand on the road doing a very good job , not only to achieve the industry's own development , but also strengthened the industry 's self-confidence . The Chinese economy is now , a year the world consumed 45% of the total amount of steel a year , 46% of coal , cement accounted for 60% , we are now a year energy consumption accounted for

Of the world's total energy consumption a year more than 20% , but GDP will account for 16% of world GDP higher. So , we are now the road is not sustainable , we are currently faced with a very serious environmental problems . The environmental problems brought enormous pressure , will push forward

Crusher industries continue to upgrade the technological level , in order to gradually improve their productivity and output .

Crusher industry according to their actual situation, certain adjustments products , energy-saving measures must be taken to improve the energy-saving equipment, large-scale technological level , and will also invest part of the funds to accelerate the upgrading of products . In the effort to make product quality,

But also increase service requirements , with a good reputation to the consent of customers of all ages around the world .

Crushers promote overall economic growth

In the development environment of global marketing under our various industries in the impact of advanced technology by other countries at the same time , communicate with foreign brands is becoming more and more networking opportunities . Crusher industry through trade shows, research cooperation and other means , to continuously improve body strength and

Core competitiveness, narrowing the gap banana screen between the developed countries .

At present , China's mining and resource utilization in terms of policy adjustments , making the utilization of mineral development costs, which gives the ore crushing machinery market has brought a no small turmoil , but also on the performance of crushers and other equipment as well as production costs put forward new demands , the government gold

And non-metallic resources are also screen machinery more concerned about the exploitation , such a market outlook for the development of mining crushing machinery, and is a kind of a good trend.

Faced with this situation , I believe that enhance the independent innovation capability will enhance crusher become an important support for the overall quality . Must strengthen technological innovation , integration of technology resources, relying on major science and technology projects , and key breakthroughs in core technologies , the development of intelligence is the key. Accelerate the integration

Walking through innovation and high-end products of the road, is broken machinery industry to adapt to the current economic development mode shift in the best way , is also China's crushing machinery evolving best direction ! Accompanied crusher industry, its strength increases also will become the future economic development

Boost power.

The use of disc feeder structure installation operation and maintenance

1 Purpose and scope of use
Disc feeder for the volumetric Vibrating feeder, it can even be continuously fed to the next device in the material to go , feed can be adjusted.
Upper portion of the cover , the degree of purification suitable for the air require a higher place .
Type upper no cover , operation and maintenance more convenient and suitable for less demanding place air purification .
Disc feeding functional feed powder, granular or small block of material . For example : coal, cement , clinker, limestone, clay and so on. Not suitable for the feed viscosity,

easy flow or flow particularly good materials.
2 Structure and working principle
The machine consists of : electric motor , deceleration devices , disc , disk sets, scraper , Pan feeder adjusting device and channel steel columns composed of several parts .
It consists of motor through V-belt , worm reducer, vertical shaft, driven by rotation of the disc . The lower disc set with worm gear connected to the upper column through the

channel connected with the silo . Motor through the motor base plate fixed to the side cover . So the entire disc feeder is hanging on

Silo below, but Channel Columns can turn around and become sitting install disc feeder .
Feed material from the hopper through the following screw gate out of the machine into the flow tube and activities on the disc sleeve . Since the rotation of the disc and the

action of the blade to be scraped , put through a discharge port plate , slip into the next device to go.
Adjusting production capacity there are three ways :
( 1 ) regulating blade position: Turn the handwheel screw through both complete. And through that the scraper blade shaft position indicator .
( 2 ) regulate the activities of the sleeve height by turning the handwheel screw complete.
( 3 ) When using the DC motor drive, the motor speed can be changed to adjust .
3 Installation and Commissioning
( 1 ) According to the silo center to find a good location , close to the center deviation of not more than 5 mm .
( 2 ) the disc must be in the horizontal position , the deviation not greater than 0.5/1000 . Channel Columns then fixed on the lower part of the silo , the feed tube with screw

gate connections.
( 3 ) hand plate moving belt, check the operation is flexible.
( 4 ) Check the worm gear lubricant inside height , and to inject the right amount of lubrication points, lubricants ( grease ) .
( 5 ) empty load test load test should be carried out after eight hours , check for anomalies. Also check the adjustment device is a flexible and reliable lag , everything is

normal , before formally put into production.
4 operation, maintenance and overhaul
( 1 ) should be carefully checked before driving scraper position and activities of the sleeve meets the requirements of the volume of feed .
( 2 ) should be carefully checked before driving the lubrication of the various parts of the history and inject the right amount of lubricant ( grease ) .
( 3 ) Subject to the disc while driving smooth rotation , and then open the screw gate . Parking should be closed screw gate and then stop.
( 4 ) Production capacity adjustment method : When using DC drive , try to adjust the speed of the method used . When AC drive , then try to use a method to change the blade

position . Only in the above two methods ( DC drive , in addition to adjust the speed , it can also adjust the blade position ) can not be

Meet the needs , the only regulate the activities of the sleeve height using a method . When adjusting, the material must be taken to the outermost edge of the disc should

maintain a distance S , in order to avoid material stuck disc , causing an overload caused by something mine .
( 5 ) operation should always check lubrication , bearings work , the part of temperature rise , if there is overheating , should be immediately eliminated.
( 6 ) Long-term operation should be regularly checked scraper , activity sleeve , disc , worm gear, belt and seal losses, in order to adjust or replace .
( 7 ) Maintenance and replacement of worn parts deadline , according to the usage of specific decisions .
( 8 ) Replacement parts can be based on the following principles demolition methods :
a. replacement worm gear and worm shaft portion of the radial ball bearings , the first to get rid of the pressure in the center of the disc pads, dish care through the two

screw holes at the top of the disc tray and pull out the disc together , and then remove the pulley cover , remove the belt , you can remove the worm gear overhaul .
b. Replace the lower worm shaft radial ball bearings or thrust bearings may be used without removing the entire worm gear box , as long as the bottom three disc set with screws

to tighten overhaul , until you feel it has so far withstood the disc . The three screws and a good long stay disk spindle after they removable reducer

The bottom of the bearing cap , remove the thrust bearing cap , could be put on the three demolition through the bearing bore of the bearing sleeve silk top out , radial ball

bearings are also together with the bearing sleeve . Replace with new bearings , you must remove the lower part of the plate with a screw cap to withdraw only after a trial .
c. Replace worm or worm bearings at both ends , as long as both ends of the gland opening , you can remove screw hole through the bearing sleeve , remove the cover and bearing

together , the worm will be easily pulled out from the bearing hole came.
( 9 ) When installing worm reducer , gear cover seal groove should be filled with dry yellow oil .

Disc feeder capacity adjustment methods and common faults introduced

1 base type and suspended disc feeder comparison
Docking disc feeder : the need to build a foundation, while supporting the poor machine , the user generally formulated weight feeder port , adjust sets, scraper plate , retaining plate

, etc., so this disc feeder installation costs high , the installation time-consuming , and because the mounting base 's sake, craft

Arranged by the very limited flexibility .
Suspended disc belt weigh feeder : improvement on the whole package , but installing the beams need special preparation , but the structure is also complex and difficult to implement

multi-port discharge .
2 disc feeder capacity adjustment method
( A ) adjusting scraper plate position: Turn the handwheel can be completed and passed through the screw shaft scraper pointer pointed scraper plate position .
( 2 ) adjust the cutting height of the sleeve : Turn the handwheel completed through cutting sleeve screw height adjustment .
( 3 ) adjust the motor speed : When the DC motor as the drive, the motor speed can be changed to adjust .
3.PDX disc feeder
PDX new disc feeder adopts advanced Hardened reducer drive, frequency control system, large diameter slewing ring , unique drive under seal and new controllable gates , its

energy consumption is an ordinary disc feeder 1/3. PDX new disc feeder adopts the most advanced plane

Double enveloping worm gear form .
PDX new disc feeder features:
( 1 ) using the easy sealing , hanging material short tube , to prevent discharge of materials for a long time and can not be cured successfully discharged .
( 2 ) the adoption of new material layer can be adjusted to control the gate , you can easily set the size of feeding amount , convenient adjustment , adjustment range.
( 3 ) the use of large diameter slewing ring structure , particularly large carrying capacity and can withstand more than 15 meters long material pressure tank mine life of 10

or more .
( 4 ) transmission structure , high reliability, long life, as used in all hardened gear transmission, the transmission efficiency is particularly high, up to 95%.
( 5 ) the transmission part of the lubrication conditions, gear, slewing bearings, pinions, etc. main drive mechanism , the use of high-quality high viscosity extreme pressure

type of load gear oil lubrication , to ensure trouble-free operation of the disc .
( 6 ) The transmission system adopts unique sealing structure to ensure that no part of the transmission mechanism lubricated entry of foreign matter .
4 disc feeder common faults and handling
( 1 ) Operating temperature mechanical
Disc feeder after 4 hours of continuous work temperature rises rapidly, the worm bearing cap and the body surface temperature can reach 89 ℃ or so , machine for a long time at

high temperature operation.
( 2 ) reducer casing serious oil spills
Because of high oil tank , oil level hole plexiglass perspective deformation , combined oil dilution , leakage serious , the most serious leakage can be achieved by the amount

of 2kg / h.
( 3 ) Worm badly worn
Worm transmission parts strong enough force caused due to box deformation, resulting in displacement of the axis of the worm two of cabinet intensity strengthened. First, the

worm drive increases the thickness of 12mm parts of three ribs ; two ends of the worm is the main load bearing parts

Increase of two reinforcing plates , so that the design to ensure the strength of the cabinet .
( 4 ) disc positioned well, when working with a load , affecting the normal worm engages the center of the turntable adds a set of positioning bearings, the bearing model for

2260 , so that from the design to ensure the disc center pair.
( 5 ) in the processing center of the worm and worm center has an offset in the spatial orientation , affecting the normal engagement , the finishing and assembly should be

performed during a tight tracking and control to ensure that the worm shaft holes two concentric , and the worm into port for grinding 0.10-0.15mm, thereby increasing Nie

Combined area smooth transmission .
Lubricant selection unreasonable design selected lubricant grades for the 20th and the 30th gear oil , because the viscosity is not enough, the worm can not form a film on the

meshing tooth surface lubrication conditions are not good , exacerbated by tooth wear , re-select lubricant. In the test has selected 200 ordinary

Industrial gear oil , and its kinematic viscosity range of 180-220 centistokes . Put into use after use 633 oil , and its kinematic viscosity in the range 288-320 centistokes ,

thus radically improving lubrication of worm .
( 6 ) disc feeder in the overall installation process, based on the bottom is not leveling ( maximum error has 12mm) is caused by a major reason for poor meshing , the process

should be installed in the field , and strictly control the level of the underlying platform to find positive , the original underlying platform is not level in the north-south

direction , the maximum error of

To 12mm, the error after leveling control 5mm / m or so.

Shaker eccentric mounting points with protective cover

Eccentric :
Adjust shaker eccentric block, mistakenly tune ends eccentric direction reversed, so that the vibration motor torque generated a space , so that the vibration motor work in a

non- normal state , thereby coal screening machine burned. Therefore, adjusting the eccentric block , be sure to pay attention to its symmetry , that both ends of the eccentric block to two

Two corresponds to , or is connected to both ends of the center of the eccentric shaft parallel with the line , can not be a different surface states.

Protective cover :
Since shaker vibration motor mostly very poor working conditions , dusty , if shields Mifengbuyan easily into the dust , causing friction eccentric operation , thus burning

motor . So bad place in the Linear vibrating screen work environment , to increase the protective cover of the seal, and after

Often shaker hood cleaning dust inside .

Vertical vibration motor excitation force adjustment

1 vertical vibration motor excitation force excitation force adjustment: Remove the additional block bolts , by increasing or decreasing the number of additional blocks to

adjust the excitation force ;
(2) the upper and lower eccentric angle adjustment: the eccentric block is a fixed block , the next block of mechanical vibrating screen supplier is adjustable eccentric blocks are compressed

using the fastening bolts on the motor shaft. Engraved on the surface of the shaft ends of the baseline , with the outer surface under eccentric mechanical rotation angle

indicated feeding ruler ,

Panasonic rotary eccentric bolts , turn down the eccentric , so that the next eccentric ruler engraved lines on the vibration screen angle reference axis aligned with engraved lines , adjusted

to the desired angle , tighten the lower eccentric bolts ; For adjusting the eccentric angle method can also be adjusted accordingly .
 The method of routine maintenance shaker

Learn belt conveyor machinery safety during operation

Belt conveyor machinery safety procedure is as follows:
1 Several mechanical conveyor running series , we should begin the discharge end , the sequence starts. All normal operation only after the feeding .
2 Run the tape deviation phenomenon occurs , you should stop adjustment shall not be reluctant to use , so as not to wear edges and increase the load .
3 conveyor prohibit pedestrians or by people .
4 working environment and sent the material temperature not higher Coal vibrating screen than 50 ℃ and below -10 ℃. Shall not be transported with a pH of oils and organic solvents constituent

materials.
5 conveyor motor must be well insulated . Mobile conveyor cables do not Luanla and dragging . Motor must be grounded reliably .
6 must be stopped before stopping feeding, unloading and other material on the belt to make deposits before parking .
7 belt conveyor installation method should be required to install a fixed basis. Mobile conveyor official before running wheels should live or with a triangular wedge brakes

stopped . In order to avoid the work place to move around. How conveyor parallel Mobile crushing plant operation, the machine and the machine between the machine and the wall of the

Should be one meter between the channels.
8 belt slipping a hand to pull the belt is strictly prohibited , so as to avoid accidents.
9 -load belt conveyor machinery should start . Other operating normally before feeding . Prohibits driving after the first feeding .
10 transport machinery must be inspected prior to use part of the operation , the tape fastener and bearing device is normal , protective equipment is complete. Tape tensioner

degrees required before starting to adjust to the appropriate level.
