fastening devices , such as Mobile crushing plant routine maintenance , the equipment inside and outside keep clean , good performance, safe and reliable condition.

        Air screen electrical control box should be kept clean to prevent dust fall into the control box , causing a short circuit or electrical component failure , to regularly

check the ground wire is good, mobile screening plant the cable connecting the device to the power switch is good, if aging should be replaced.

        Air screen host , motors and fans inspected once a year , the amount of added oil, remove dust inside the motor .

        With a sieve shaker shaker machine must be repaired once or twice a year , each time you want to add oil maintenance , connecting bolts to tighten .

        Replace the airflow mesh sieve to ensure uniform tension , fixed at both ends of the rope , you need to adjust the screen edge fastening edge .

        Second, common faults and troubleshooting

        1, when the capacity is mainly the application of screening tests to detect the material meets the screening requirements.

        2, when the volume suddenly increases taken when handling product testing analysis, if unqualified finished , check the screen is intact.

        3 , when the material suddenly not working .

        ( 1 ) should check whether the fan is normal, if the fan flow reduction, should examine discipline .

        ( 2) Check whether the discharge auger does not rotate , you can not discharge .

        Third, pay attention to matters

        1, the machine should not be screened with a viscosity, water content greater than 5 % of the materials and flammable and explosive materials.

        2 , the same type of air screening machine, the greater the corresponding mesh screening material yield.

The current trends in the development of mainstream mining machinery

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 .

Cleaning sieve works with the use of

   The aircraft in the material fed from the feed inlet screen cylinder , the playing board by rotating the impact and delivery role, so that the material in the agglomerate material is broken mobile screening plant up, and with the surface of a plate with a circular motion around the cylinder , the centrifugal force under the influence of the material is less than the sieve sift quickly from the lower body from the plane, close to the screen cylinder cleaning brush ready to hang on the crushing plant sieve to remove material on the tube . Greater than sieve large miscellaneous transportation in playing the role of the board under the direction of exports to the passage of large miscellaneous discharge.
      Movable cylinder cleaning sieve is when food grain storage clean impurity ideal equipment , but also for grain processing, grain and oil processing industry cleaning equipment , the replacement of the screen may be different with different grain cleaning , in the local climate conditions outdoor work under load continuous, stable and reliable removal of impurities in food , for wheat, corn , etc., is your ideal device . cylinder cleaning screening for small 20-30t / h medium 30-50t / h large 80-100t / h.
   

The use of cleaning sieve

   The aircraft in the material fed from the feed inlet screen cylinder , the playing board by rotating the impact and delivery role, so that the material in the agglomerate material is broken up, and with the surface of a plate with a circular motion around the cylinder , vibrating screen manufacturers the centrifugal force under the influence of the material is less than the sieve sift quickly from the lower body from the plane, close to the screen cylinder cleaning brush ready to hang on the sieve to remove material on the tube . Greater than sieve large miscellaneous transportation in playing the role of the board under the direction of exports to Linear vibrating screen the passage of large miscellaneous discharge.
This sieve type original common rice, noodle factory in liquidation phase after the procedure . 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 .
