With the development of coal industry and the improvement of coal mining mechanization, the content of fine particles in raw coal is increasing, and the content of slime in products is also increasing rapidly. The increase of moisture brings difficulties to slime recovery and dehydration. However, the one-time investment of slime water treatment system is relatively large, High frequency vibration dewatering screen Compared with disc vacuum filter, sedimentation filter centrifugal dehydrator and horizontal sedimentation centrifugal dehydrator, it has the advantages of simple structure, low cost, convenient maintenance, large processing capacity, simple process system and low cost of recovering slime.
1. Vibration motor drive, low investment cost.
2. The baffle at the feeding position of screen frame is opened to increase the processing capacity of raw materials.
3. Polyurethane screen plate as the screen surface, wear-resistant, corrosion-resistant, long life.
4. The hook bolt is fastened and the side plate of ore screening is strengthened, which is strong and durable.
5. Rubber spring shock absorption, low noise.
6. Double layer screen, mesh aperture, stainless steel screen and galvanized screen can be customized for specific purposes.
Dewatering screen is mainly used in wet sand production line. It is generally used with wheel type sand washer or screw sand washer, and can also be used alone for dewatering of tailings slurry. The water is discharged from the screen through two eccentric sections through the eccentric motion of the screen.
Precautions for use:
After the test run, check that the above contents are correct, and re tighten all fasteners. The screen and all parts are fastened in good condition and can be used formally. Before that, the following work should be done well:
1) Training of operators
It is necessary to understand the structure and simple working principle of each part of the equipment; before operation, it is necessary to make preparation for start-up, check that the rotary parts are flexible and free of jamming, the screen screen is in good condition, all parts are not loose, and the bolts are tightened.
2) No load start and stop
Vibrating screen is generally used in crushing and screening equipment or washing process, requiring no-load start and stop of the screen machine. Therefore, it is necessary to follow the principle of reverse process start-up and process flow shutdown. Except for special reasons, parking with materials is not allowed. When there is accumulated material on the screen surface, it must be removed before starting. Feeding can be started only after normal operation.
