Is the use of complex rotary shaker vibration transducer excitation arising from the work

Is the use of complex rotary shaker vibration transducer excitation arising from the work. Vibrator on the screen surface to produce rotating weight makes the plane swing vibration, and the lower rotating weight makes the screen surface to produce conical Coal crusher machine vibration, which makes the effect of the combined effects of the screen surface to produce complex rotary-type vibration. Its vibration is a complex spatial trajectory curve. This curve is a circular projection in a horizontal plane and Dewatering screenin the vertical plane of projection is an oval. The regulator, rotating hammer excitation force can change the amplitude. Adjust the upper and lower phase angle hammer space, you can change the shape of the curve of the screen surface and change the trajectory of the trajectory of the screen surface materials.

In the purchase of mine shaker details can not be ignored

Buy a good mine shaker is our common aspiration , but there are many in the purchase of the details we need special apron feeder attention. If you choose properly, they will bring some

economic loss for the company , so mine shaker when choosing what to pay attention to what issues it,

For the shaker , the most important part is simply vibrating motor , screen and bearings , we have to be feeder breaker more careful when choosing these three components , I believe that as

long as we do compare , buy out a high-quality , good performance the mine shaker is not a problem .

   We first have to look for when selecting a few to compare , choose a higher bid letter manufacturers, not blindly pursue cheap and runs the risk that people often say that no

good cheap goods , and this sentence is not unreasonable . Something inexpensive production costs inevitably low , so that the

Quality is bound to decline, coal mining machine the ancients often said to shop around to buy things , not only is the price ratio , more important is the quality. Now we come for several

important parts to this simple analysis should buy special attention.

   Select the vibration motor is particularly important, the motor is the soul vibrating screening equipment , as well as the source of its power , the choice we have to

consider the actual production situation carefully choose the right size of the motor . Because we selected motor power over the General Assembly phenomenon caused by power idle

,

Waste of resources ; If power is too small will result in ultra- load operation , the motor may burn out . In choosing our comprehensive consideration of factors of production

and boring nature.

   Heart shaker screen is vibrating sieve is good or bad depends entirely on the screen , the screen pore size , pore shape , the thickness of the mesh , the mesh material such

problems that we need to consider. Today we produce mostly made ​​of stainless steel mesh , its resistance

With a degree should be understandable. Furthermore, is bearing selection , choosing a good bearing not only economical and durable, and will extend the life of the shaker , and

bring more economic benefits. Choose a good quality shaker is only the beginning , and not the end , but also

We need to care and maintenance in production activities .

Mine is expected shaker in China there are broad prospects for development

Mine shaker is gradually being applied after the development of China's mining industry matured to the mining industry , which is mainly used for ore particles are crushed after

the screening , the different size of the ore crusher manufacturer particles separate. In the past, because of the low level of mechanization , so that our

Ore mining and extraction of precious metals levels were very limited. Most of the time the machines are imported from foreign countries , China's level is limited to the

imitation of foreign imported machinery . Later, on the basis of the purchase of the equipment plus their imitation of the changes and added into a

Something new , the functionality of these devices have been gradually improved. In the early development of the double roller crusher mining industry , screening equipment we use is the oldest sieve

, when the screening is completely manipulated by hand , it is efficiency and the benefits that we are not conceivable the

. Later, with the continuous development of society , the old equipment can not meet the needs of production, upgrading technology advances and equipment is evolving needs of

the community . So modern Linear vibrating screen machinery to produce and gradually occupied the Chinese market .

   Our country has a very rich mineral resources, these mineral resource contains a lot of precious metals , such as: gold , silver, lead , copper, nickel and other metals . Ore

mined our country greatly promoted the development of China's economy , many people are turning to our ore mining

Industry , mineral industry led to the development of many other industries , including mining shaker. Our mine shaker in the early creation to now has gone through many

generations of updates, we all know that development is of overriding importance , in order to follow the development trend of the times , they need

To continue to improve and enhance . Dressing shaker in the industry not only in mining ores , and is now also applied to the recycling of tailings into . Uncontrolled

exploitation of mineral resources will make soon exhausted , it was found in the abandoned tailings also contain a lot of

Not mined value , if they exhumed benefits are fairly objective , so there are a lot of people have seen this opportunity and increase investment in recycling of tailings .

   Today, with the requirements of sustainable development and constantly made ​​, saving resources has become the hottest topic of the moment , we have to comply with the

production of energy-saving machinery and equipment , so our vibrating screening equipment among future development, not only toward large-scale production , but also to the

fine

Continued progress and environmentally friendly direction . Changes in national policy but also for the country's mining provides a good space for development with the

development shaker , shaker mine development in China has a very bright future .

Mine shaker significance for sustainable development

    Mine shaker rely on two vibration motors do the same in the opposite direction from synchronous rotation , so that the whole supported on shock absorbers to make linear

vibrating screen machine , the material from falling into the feed end of the screen box , fast forward, loose , coal crusher machine transparent screen, complete the screening operations . Today,

China's economic development is very fast

Speed ​​, people began to focus on environmental sustainability and social development , sustainable development put forward that we can not eat rice fathers , sons off the road ,

which requires us to consider in crushing equipment the development of our economy for future generations , not uncontrolled mining, off the resources of future generations

. On that country 's mineral resources and coal resources for it, these are non-renewable energy , if we unrestrained exploitation , in the near future will be depleted , and

that our children and Crushing equipment grandchildren how to do it . So our proposed plan for sustainable development, which

Means of mechanical equipment to go up a level , toward the direction of energy conservation .

    National 12th Five Year Plan proposed to provide a new platform for the development of China's machinery industry , but also for the continuous development of our industry

shaker provides an opportunity . The mine will be toward the direction of light , green energy development shaker, shaker Although mine

Perfect, but in order to conform to the trend of social development , we need continuous improvement .

Mine selection and routine maintenance shaker motor

Vibration motor is one of the most important mining shaker parts , it is recommended to be careful in the choice of our choice in daily production activities should pay special

attention to maintenance, to extend the crushing plant life of the motor , which can be for enterprises to create their own higher interest value . The interests of all enterprises

Pursuit of a common goal , we purchase a machine , we must carefully calculated to bring its benefits to our company and the expected value of the scrapped after . Mine shaker

is not generally applicable to complete crushing plant a continuous grading operations where large materials are generally used dual-motor drive . Our mine

Shaker to use more energy-efficient motor as vibration source , lighter body such equipment quality , easy to transport , high efficiency, relatively wide range of applications

. Mine shaker vibration motor excitation , damping spring steel springs or rubber , wear-resistant belt weigh feeder material mesh sieve , sieve sealed or open

Boxes and other domestic and foreign advanced technology and advanced self-synchronous vibration principle .

   We pay special attention to the selection of the motor shaker when buying mine, motor type, power, life , and prices are all we need to know the information, we need to

carefully read the nameplate, understand the information and screening equipment . Select the motor too big too easy too easy

Small enough you can , too easily lead to waste of resources, too small easy to overload the motor is running , it may cause the motor to be damaged. We need a comprehensive

selection of considering all the factors , if the material particles larger screening , such as sand and gravel , but also higher production requirements , we

To select the appropriate power of larger motors. If the particles are more delicate materials screening , screening efficiency requirements are not high , we can reduce the

power of the motor proper contrast .

    To prolong the life of the shaker , the quality is good close to useless , no matter how good the quality of the stuff , if you do not care when using them , will soon be

scrapped, so we should pay attention to routine maintenance of the motor. Most vibration motors installed in harsh environments , large dust

Place , nor the cooling fan motor itself , thanks to the natural cooling , the correct use will extend the life of the motor and the efficiency of the motor, so routine

maintenance is particularly important . So we need to regularly check for vibration motor , found that the problem should be treated , not

Allows legacy issues interfere with our normal production , serious and even cause the motor may be burned . Vibration motor maintenance work to do , you can easily extend the

life of the shaker , for the company to create greater efficiency.

Mine shaker introduced in various industry applications

Mine shaker is a new and efficient screening equipment , mainly used in metallurgy, mining, coal , building materials, electric power, chemical and other industries. Screen

variety, have woven mesh , mesh, polyurethane mobile crushers for sale network and crack net. Has a large capacity, high efficiency, convenient mesh exchange ,

Installation and maintenance simple and so on. Mine shaker also been widely applied to all walks of life to go into , for China's economic construction and make a contribution .

1 in beneficiation industry applications :

    The main Feeding machine beneficiation industry is mine shaker in the beneficiation process is generally the first rough ore screening , and then further refined during

the screening . Our mining industry has had a certain history, so that mine shaker is a certain calendar

History of the . Promote the development of mineral resources in China's economic development , for Semi-mobile crushing plant the development of vibration screening industry provides the opportunity

shaker in the development of processing industries will scale with the expansion of mining and continue to grow and develop.

(2) in the flour industry applications :

    We northerners are pasta, three meals a day were almost inseparable from the surface , raw wheat flour , wheat flour need to go through to become a very elaborate process .

I remember as a child back home to eat the wheat flour is to grind your own home , and will put wheat

Until after the machine , waiting for pick up flour and bran . Bran is a product of the pulverized wheat bran , wheat , after the first complete after pulverization by the

sieving action of white flour bran got left out of the screen . In fact, the bran and flour is distinguished shaker , because

Production of flour industry is large, so people usually mine shaker equipment.

(3) In the beverage industry applications:

    What we usually drink fruit juice , beverage production processes that are applied to the mine shaker screening function. After the fruit is crushed seeds inside and

contains a lot of impurities , while the beverage we produce relatively high , so they need to pass the screening effect,

The juice to remove impurities and clean , but mine shaker become the first choice of many bosses .

Mine sieve shaker in the coal industry

Coal is one of the most valuable non-renewable resources, we all know that coal is a very valuable resource even after millions of years before the formation of precipitation .

Since the discovery of the underground mobile screening plant geology bears our country is very rich in coal resources , exploitation of people began wantonly , coal

Charcoal industry a lot of self-made rich entrepreneurs . Our Shanxi is rich in coal resources , so there are a lot due to open in Shanxi coal mine and rich people . Some time

ago the uproar in the online Shanxi coal crusher plant manufacturer bosses , the daughter married Lincoln wedding convoy , public

Star singing to help out coal boss is one of them.

    In fact, the coal and double roller crusher carbon are two different resources from the appearance point of view , are generally small particles of coal , while the carbon material is generally

larger particles of carbon, coal much larger than the hardness , resistance to carbon ratio of the coal burning, Therefore, the price of carbon is higher than coal . When

resources are mined coal , coal

And carbon are mixed with each other , and some entrepreneurs wanted a way to coal and carbon separate, just getting used when screening equipment is old-fashioned , low working

efficiency . Now people invented something called mine shaker equipment in the coal industry has been an extremely wide range of applications

Application of this screening equipment , screening of difficult problems to solve .

   Some time ago a classmate and chat , ask him where he said at a coal mine in Shanxi , of course , and certainly not to coal mining , they are engaged in post- graduate work

in this profession , is mainly responsible for the production of coal produced by wastewater treatment so that it can discharge standards , reduce

Pollution of the environment . In fact, in the coal mining industry in the application not only to coal and carbon shaker distinction can also be used for pre-treatment did your

recovery and on production of wastewater. When slime recovery of the shaker can intercept them relatively large impurities , making the recovery of coal

Mud is more pure . In mine wastewater pretreatment with grill shaker is the equivalent role , its role is to remove large particulate matter in the effluent . After pretreatment

of wastewater into the depths after treatment system for further processing can discharge it.

   State just introduced the " 12th Five Year Plan " clearly indicates the state of the industrial structure of the coal industry in the next five years to be adjusted during

the construction plans for the mine 's coal industry reform will enhance the technical level , it will pull mine mechanical requirements , particularly shaker

And other screening equipment .

Vibration isolation capability round griddle and screening efficiency

Circular vibrating griddle ( round vibrating screen ) due to vibration griddle only one axis , also known as single-axis vibration griddle . Circular vibrating griddle ( round

vibrating screen ) screen box China Vibrating Screen trajectory is circular or oval named.

    Circular vibrating griddle ( round vibrating screen ) when activated and deactivated , since the amplitude of the resonance region , the screening machine speed will

increase , vibrating screen manufacturers causing severe overload spring to shortened life expectancy , belts easily damaged , and it will affect plant construction safety. Dongyuan round vibrating machinery

production

Shaped vibrating griddle increased vibration absorption device , and eliminate vibration device is used to eliminate this resonance phenomenon , to ensure safe mining operations

. When increasing the rotational speed of the vibrator to about twice the critical speed , the eccentric block pop work required to produce the vibration force and amplitude.

When parking , vibration

When the resonant actuator speed to about twice the speed , pull back the spring eccentric vibrator basically in flat horizontal position , does not produce exciting force ,

will not increase the amplitude of the screen box , to eliminate vibration purposes.

    Circular vibrating griddle ( round vibrating screen ) is divided into ordinary circular vibrating griddle ( round vibrating screen ) , and self-centering vibration griddle ,

the difference between them lies in the different structure of the vibrator , the former center of the pulley bearing center and located in the same a straight line , when the

vibration griddle operation , pulley will immediately sieve

Boxes together vibration, thus causing repeated stretching of the belt is leaving easily damaged and requires a smaller amplitude. Because of these drawbacks, this shaker has

been rarely used in the production process .

    Self-centering vibration griddle center is located between the center pulley and the center of the eccentric bearing , and to the center line of the eccentric pulley and the

center of mass of the vibration body synthesis , therefore , when the vibration of work griddle pulley do not shake along with the screen box , making rotary motion from

And also with a larger amplitude in order to improve screening efficiency. Thus , self-centering vibration griddle developed rapidly, to get a wide range of applications . Mine

production is currently used in circular vibrating griddle ( round vibrating screen ) generally are self -centering vibration griddle this type.

Mine shaker artificial stone production line in important applications

Roads, buildings and other plant materials , often require public sand and gravel production line , the set of aggregates production line equipment will be able to meet the

needs of stone and artificial sand production requirements simultaneously .

Prevalent in the domestic construction industry today , the building materials industry also will usher in opportunity, strong demand for construction materials throughout ,

especially in the cement industry has been greatly developed . The cement industry in the new development opportunities , but also affects other industries, such as the

development progress gravel , cement industry

And gravel industry closely , it can be said gravel industry in order to promote the progress of the cement industry. However, the development of any connection with crushed

gravel industry related machinery and equipment , crusher equipment choice directly affects the yield and quality of gravel , cement production while also resulting in a greater

impact .

    From the 1970s into the new century, a 12-year half-century years, China has experienced an unprecedented reform and opening up , our great country both in terms of

political, economic, cultural and social life , or in the various ethnic groups , regions and each aspects of the individual spirit have taken

Had a tremendous , tremendous changes look . For half a century , China's building materials industry is achieved rapid development. Production of building materials industry as

a gravel one of the main varieties also increased sharply , which also led to the gravel industry from behind even some of the original raw

Producing state in the direction towards the rapid development of industrialization .

How to choose the griddle screen

Crushing machinery enterprises to enhance the capability of independent innovation

China is the mechanical manufacturing country , but not power. Chinese production has accounted for a large proportion of broken machinery of global construction machinery

production, but compared to some crushing and screening plant high-end equipment with the international advanced enterprise products, there is still a wide gap . Then, " Made in China" broken machinery

The status quo is what it?

According to the status quo stone feeding machine of China's discovery : China to create a " big but not strong Chinese crusher crusher manufacturer has been shouting for years ." To build a world -

class brand "slogan , the status quo is not satisfactory , the crux of what ?

"Made in China " can be broken machinery products sold overseas in recent years , has indicated that the quality of Chinese machinery products has been recognized by the world.

The data show that China's crushing machinery sales and sales have leapt to the forefront of the world , is expected in 2012 China crusher

Industry sales and sales growth will be above 20% , with exports expected to reach nearly ten billion U.S. dollars .

Although there are risks in overseas M & A process , but Chinese enterprises " going out" is inevitable. In addition, through cooperation with foreign companies , China 's

position in the world has improved.

China Machinery Industry Association crushing official said , China crushing machinery enterprises to enhance the ability of independent innovation. The central government

introduced a lot of " Twelfth Five-Year Plan" and the broken machinery industry relevant if these plans can be implemented , will promote China crushing machinery enterprises

upgrading.

In addition, the development of bad business mainly because of broken machinery hydraulic system and engine problems , because these components require companies in terms of

precision casting and machining has a very strong ability . Of course , this also with the overall level of national basic industries associated with it. A

Hydraulic valve includes more than 400 parts , the United States , Japan and other countries can be assembled in the country is good, but we can only rely on imports .

Currently, developing countries called the "three basic industries" ( mechanical foundation , basic manufacturing processes and basic materials industries ) , if these policies

can be implemented , China's basic industries will be able to enter a new stage , China's crushing machinery products with foreign countries the gap between the products on

Will become increasingly smaller .

How to do mine shaker routine and periodic maintenance

Mine shaker role and principles:

     Fundamentals by vibration motor system installed on the lower end of the hammer shaft (unbalanced weight, the weight if the change in the upper and lower portion of the material can change the phase angle of the direction of travel), the vibration of the motor rotational movement into horizontal, vertical, Three-dimensional tilt movement, then this movement to convey to the screen surface.

Shaker structural features:

    1) unique mesh Belt feeder design for easy and quick replacement screen (only 3-5 minutes), in addition to this design allows the use of various mesh (nylon, special dragon, PP mesh).

2) screening machine design; compact and easy to assemble, a person can operate sieve machine.

3), and other related brands compared with the larger screening area and high efficiency of processing power.

4) His mother weight feeder fully supported fine mesh net, so fine mesh can be scored longer life, and lower consumables use fine mesh, silt long production process can reduce a lot of costs.

Shaker routine maintenance:

1, before the start:

(1) Check the coarse mesh and fine mesh for damage

(2) whether the locking ring beam for each group

2, start time:

(1) Note any abnormal noises

(2) whether the current stable

(3) whether the abnormal vibration

3, after use: After each use that to clean up.

Shaker regular maintenance:

Regular inspection coarse mesh, fine mesh and springs without fatigue and damage, whether all parts of the body resulting from damage due to vibration, the site must be added lubricant lubrication.

Press the mine shaker structure to classify what

First we look at mine shaker structural features:
     ① The eccentric block as exciting force, strong exciting force.
     ② sieve and screen box beams using high strength bolts, simple structure, convenient maintenance;
     ③ The tire couplings, feeder breaker flexible connection, smooth;
     ④ the use of small amplitude, high frequency, large angle structure of the machine high efficiency, handle the largest, long life, low power consumption, low noise
Now we are under the mining vibrating screening machine structure and working principle into the following categories:
     (1) Fixed 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 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, screening efficiency is low, generally only 50-60%.
     (2) roller mine shaker: Face by scrolling horizontally arranged shaft consisting of a plate feeder root, shaft with plates, fine material from the gap between rollers or plates through. Bulk material from one end of the roller driven to move to and from the end of discharge. Concentrator rarely use this sieve.
     (3) a cylindrical mine shaker: working portion is cylindrical, the screen rotation around the cylinder axis, the axis of the general inclination of downloading into. The material fed into the cylindrical end of the fine material from the cylindrical working surface level through the sieve, coarse-grained material is discharged from the other end of the cylinder. Sieve cylinder low speed, smooth, good power balance. But its easy to plug the sieve screening efficiency is low, the work area is small, low productivity. Concentrator rarely use it to make screening equipment.
     (4) planar motion mine shaker: the body is one plane swing or vibration. Its flat trajectory is divided into linear motion, circular motion, elliptical motion and complex motion. Shaking sieve and shaker in this category.

Feeder and mine shaker motor power calculation method introduced
By analyzing the feeder and vibrating screen for mine start-up process , calculate a reasonable motor power data . In order to ensure smooth transportation of ore and unloading process , so that the entire mine production safety and reliability.
    As bauxite and limestone mine working environment and the special nature of the ore ore transportation and unloading process, ore often bond , resulting in ore bin blocking stagnation , affecting the normal production of the mine . To this end we add in its process design inertial vibration feeder and mining

Shaker .
    Determining inertial vibration feeder and mine shaker motor power parameters during power transmission and calculation reasonable choice is a very important issue, it is not only inertial vibration feeder and mine shaker important condition for normal operation , but also the power consumption of reasonable

Important condition .
    In traditional engineering design, inertial vibration feeder and mine shaker motor power to determine the parameters are determined by the empirical estimation . For example, from the east to the source of mine shaker design of a limestone crushing and screening system is expected to treat ore 4000kt / a.
    Crushing and screening system process is used 4m3 mining shovel loading , transported to the crushing and screening system of limestone ore particle size of 1000 - Omm, combined with product size requirements , designed with coarse, medium and fine crushing process closed Rd .
    We can see feeder and mine shaker in the crushing system using high frequency , the quality of the product plays an important work
Purposes. Feeder and mine shaker motor power is calculated in several ways , some of which belong to the empirical formula calculation methods , they can only choose this type of device power preliminary determination . Generally larger error , if you want to calculate the reasonable power , we must analyze such

Mechanical boot process , in order to obtain a more reasonable motor power data . The result of this calculation in the limestone crushing system transformation process has been verified. Engineering design has been completed , the mine on the feeder and vibrating screen selection, in which the motor power

Sure did not conduct detailed calculations , but empirically based formula to determine the amount of processing and mining vibrating screen feeder motor power parameters , the project was designed to determine the theoretical basis of motor power is not very good . With the level of technology continues to progress, vibrating feeder and

Mine shaker motor power parameters calculation method has also been some improvements. By analyzing the feeder and vibrating screen for mine start-up process , calculate a reasonable motor power data is a relatively well , are more likely to achieve a calculation. The following calculation of this

Method for simple introduction.
l mine shaker feeder and start the process of
    Feeder and mine shaker normal quality of work is done by the inertia of the vibrator with eccentric drive in which the body produces a continuous vibration , so that the material is effectively conveying or screening . The core part of the vibrator is a constant speed rotating eccentric masses . When the feeder

And mining shaker is vibrating screen classifier started, the eccentric mass vibrator within the specified time , the still reaches operating speed to achieve normal operation , all of the boot process to complete .
    To achieve this the boot process must be in the eccentric mass vibrator plus a maximum torque to overcome the resistance moment vibrator , static torque and acceleration torque to achieve mine shaker feeder and the normal starting , stable operation of the working condition.
   Previous literature describes some of the mechanical vibration motor power calculation method ; based on practical experience based on empirical formula more calculation errors. The crushing and screening plant text to mechanical vibration during start to calculate its power , it is more reasonable. Designed by the hospital of Dalian Anshan certain

Limestone crushing and screening system, transformation, loading positions on , PCK1460X1300 hammer crusher under mine shaker is calculated using the above formula to determine the mine shaker motor power parameters , from the fundamental solution to the burning motor phenomenon, to ensure ore transportation and

Unloading process smooth, so that the entire mine production safety and reliability. Of course, mine vibrating screen and vibrating feeder actual work process is also more complex , more sophisticated calculation methods should be carried out a study .

As the particularity of grain production , in order to achieve satisfactory cleaning effect , in the selection and use of equipment to do the following: ① granary is now equipped with complete sets of equipment production operations are 50t / h, compared to rice production , noodle factory larger and larger impurity grain on the market , the choice of such a sieve type, note that the best choice sieve sieve surface width 1.8m , 1.8m width as the screen type is a double feed, can fully effective use of the width of the screen surface sifting , and 1.5m wide sieve screen surface is a single feed port type , the material layer is concentrated in the middle of the screen surface , the screen surface itself is narrow , plus the problems, the flow can not be meet 50t / h production requirements. ② The sieve -type light impurities removal efficiency is higher, can better meet the production requirements , but be careful collection hopper to promptly clean up , it is worth noting that boot with particular attention to light impurities auger rotates in correct direction , otherwise once the operation reverse , it will cause clogging . ③ The sieve -type small miscellaneous cleaning effect is better, because the screen surface with a self-cleaning ball , clogging . However, the screen on the ropes, and other fibrous valley shall be very sensitive to impurities . If too many of these impurities , cleaning is not timely , it will live in a big mixed paste the screen surface , so that the effective screen management area is reduced , causing some food grain exports flow to large complex , affecting equipment production and cleaning effect . Wuhan, central grain depot in general use, a car will stop after the goods under the clean up once , such impurities for a long time , 20min non-stop on the machine easy clean up once .

Operate pneumatic grain dryer should pay attention to what

An operation :
1, first turn off limit damper to reduce fan load , load up the air starts running.
2 , the start button, the jog buttons double roller crusher look, whether the fan is transferred, must be used to keep the motor running forward .
3, the boot process : first open unloader , and then open fan.
4, the suction nozzle when the grain is not completely in contact with the absorption , to maintain the Belt feeder tube diameter of 1/ 3 , the inlet channel .

Second, Troubleshooting:
1, the use of the process , if we find production decreased , the need to open the observation hole , look, set of glassware filter is clogged.
2 , If the fan is running, the machine has a larger noise or jitter sense , turn the fan Tim miscellaneous mouth, look , fan blades are sticky dust. If the fan stops must come

after the shift , one by one blade please finish off before use rationale .

Talk about the application of the principle cleaning sieve
