未标题-3 WRIKU's High Frequency Vibrating Fine screen(Stack Sizer) can realize wet classification of wet fine grain minerals , which is widely used in such mineral processing of coal , Minerals chemical raw materials and food processing industries. It is especially used for coal preparation plant to precise coal slime classification , reducing the content of coal slime and improve concentrate quality.

Fabrication Features

1. The vibration system of the screen is fully enclosed vibration motor or vibrator, which is light in weight, reliable in operation, low in noise and small in maintenance;

2. The movement track of the screen machine can be circular or linear according to different screening requirements;

3. Vibration frequency of sieve machine is 16 ~ 50Hz; Amplitude 0.5 ~ 2mm;

4. The installation inclination of the screen surface is within the range of -5 ~ 25°, which shall be determined according to the screening requirements of different materials;

5. Patented polyurethane screen with high opening rate, wear resistance, easy to block, and long service life4000 hours, more than 15 times of the stainless steel wire mesh;

6. Patented non-metallic shear spring, with stable and reliable operation, small base dynamic load and low noise;

7, the utility model patent shear spring seat plate, make the shear spring maintenance convenient, improve the safety performance of the whole machine, greatly shorten the spring replacement time, improve the screen machine can be used;

8. The damping device of the utility model patent shortens the time of starting and stopping the sieve machine passing through the resonance zone, which plays a protective role on the shear spring and extends the service life of the shear spring.

9. Equipped with feeding boxes suitable for the screening of different materials, reasonably distributed to improve the screening efficiency and reduce the impact of materials on the screen surface at the feeding end;

10. Spray system is provided for wet screening and pulping; The dry screen is equipped with fully enclosed dustproof cover, with maintenance access door on the side, easy to disassemble and good sealing effect, which can reduce environmental pollution;11. The sealing design between the screen and the screen body effectively avoids the effect of the leakage of the screen on the yield;12. Multi-layer space superposition parallel feeding system, increase the production capacity of the system, with the minimum floor area, the simplest system pipeline connection, the lowest engineering cost and maintenance workload, to achieve the maximum screening capacity and work efficiency.13. Material selectionThe side plate adopts Q245R; The side plate protection material is stainless steel; The material of the sieve plate and the lamination of the sieve plate is polyurethane; The material of feeding trough and sieve bottom funnel is Q345. All contact surfaces with materials are coated with polyurethane wear resistant layer.

Several Analyses Affecting the Screening Efficiency

1. At the beginning of the debugging stage, because each device has not been debugged to its standard working state, it will appear:

A. Low pulp concentration;

B. Large feeding quantity;

C. There is a big difference between particle size composition and design parameters, and more particles are produced;

The above three points will greatly reduce the screening efficiency, increase the load of the beneficiation process circulation loop and reduce the output whether they appear alone or in combination during the commissioning stage. The solution is to adjust the design parameters of each equipment before screening in the eight-selection process.

2. When there are too many material particles close to the size of the screen hole, when the screen surface cannot self-clean the material blocking the screen hole during the vibration process, more serious hole blocking phenomenon will occur with the increase of time, which will greatly reduce the screening efficiency, increase the load of the mineral processing cycle loop, and reduce the output. The solution is to adjust the material size composition or screen hole size to reduce the material content close to the screen hole size as far as possible.

3. the nature of the material itself is adsorptive, easy to block holes, difficult to screen, resulting in the reduction of screening efficiency.

Feeding Hopper Installation

It is suggested that the bottom plane of the distributing hopper is 300~800mm higher than the top of the feeding box. Excessively high distributor installation will increase the erosion damage by slurry on the sieve panel and reduce panel's service life .

The production of maintenance ramps can be made according to the diagram in below, which is conducive to the daily replacement and equipment maintenance. The distance between the ramp platform and the main body of the sieve machine shall be no less than 80mm, among where there shall be no contact connection
