Currently existing artificial sand production line, the vast majority of the wet process, no matter what form of sand washer, the biggest drawback is fine (more than 0.16 mm particles) erosion is serious, some even lost more than 20%, this not only serious loss, but also seriously affect the grading of sand, grading is not reasonable, thick fineness modulus, greatly reduces the sand mechanism of the quality of the products. Too much fine sand discharge, but also can cause the pollution of environment.

To solve the above problems, our company successfully developed a series of KD fine sand recycling system, this system is that our company absorbing foreign advanced technology, combined with the actual situation of sand powder designed with advanced level of the fine material extraction device, is widely used in hydropower station sand aggregate processing system, glass raw material processing system, the artificial sand production line, coarse coal slime recovery of coal preparation plant, and environmental protection engineering (mud purification) and so on, which can effectively solve the problem of fine sand recycling.

Performance characteristics:

1. The traditional artificial sand wet processing technology, artificial sand wash mud, dehydration using spiral sand washer, the loss of fine sand in artificial sand can hardly control. The fine sand recovery system is proposed, which can effectively reduce the loss of sand, make its are controlled within 5% to 10%, well solved the artificial aggregate processing system in the finished product sand fineness modulus on the high side, the problem of stone powder content is low.

2. The vibrating screen using the live longer than other types of polyurethane sieve sieve, without blocking.

3. The brigade is lined with pu, improve the service life of the device, can be successfully completed slurry concentration, liquid clarification etc.

4. The maximum recovery of total emissions in 85% of the fine particle materials, other equipment incomparable technical advantage with the manager.

5. Fine grained fully recycling, reduce the workload of sedimentation tank, reduces the cost of tank cleaning.

6. Reduce the time of fine materials piled up, can direct transport, supply market.

7. According to the different requirements of users, the design of different solutions.

Structure:

By the motor, slurry pump, cyclone ZKR linear vibrating screen, cleaning tank, container, etc.

Work process: cyclone carry sand and water mixture to pump, centrifugal grading enrichment of fine grit mouth for vibrating screen, after sieve dehydration, effective separation of fine sand and water, a small amount of fine sand, clay and so on the return container back to cleaning tank, cleaning tank liquid level is high, the discharging mouth eduction. Linear vibrating screen recycling material weight concentration of 70% to 70%. Adjust the fineness modulus may be changed by changing the pump rotation speed, cement mortar to try and regulating the overflow water, replacement of sand mouth. To complete their cleaning, their dehydration and classification of three functions.

Working principle:

For the centrifugal slag pump cleaning of the tank in the sand and water mixture to hydrocyclone centrifugal grading enrichment of fine sand by grit mouth for the vibration sieve dehydration, after sieve dehydration, effective separation of fine sand and water, a small amount of fine sand, clay and so on will be returned to the box back to cleaning tank, mixed reflux of mixture in hydrocyclone, to be sent to the cyclone separation again. When cleaning tank level is too high, the discharge outlet. May be changed by changing the speed centrifugal pump, slurry concentration, adjust the water overflow, replacement of sand mouth to achieve fineness modulus adjustment, so as to complete their cleaning, their dehydration and classification of three functions.
