1. Fine sand recovery device structure:

Fine sand recovery device consists of electrical machine, slurry pump, hydro cyclone, ZKR line vibrating screen, purge tank and material returning bin, etc.

2. Working process of fine sand recovery machine:

The sand and water mixture is sent to hydro cyclone. After centrifugal grading enrichment, the fine sand is sent to vibrating screen by sand sinking mouth. After dehydration by vibrating screen, the fine sand is efficiently separated from water and a few of fine sand and clay come through material returning bin then come back to purge tank. When liquid surface in the purge tank is high, the discharge hole can adjust the liquid surface. The weight concentration of recycling materials in line vibrating screen is 70%-85%. Adjusting fineness modulus can be realized by changing pump rotation speed, changing pulp consistency, adjusting overflow water and changing sand sinking mouth. By the process above, the fine sand recovery system can finish three functions, cleaning, dehydration and grading.

 

3. Advantages of fine sand recovery machine: 

1) Effectively reduce the fine sand losing quantity, and make it in the scope of 5-10%.
2) The vibrating screen utilizes polyurethane screen cloth, which has longer life compared with others and uneasy to be blocked.
3) Inner the polyurethane, strengthen the whole device service life, it can smoothly finished the work of condensing slime and clearing the liquid etc.
4) The maximum fine grain materials quantity recovered from the total effluent is 95%, so it has unsurpassed technology and economic advantage compared with other equipments.
5) The find sand are recovered sufficiently, you can reduce the sedimentation basin workload and Low its clean cost.
6) Reducing nature stock time of the fine material, they can be transferred directly and supplied to the market.
7) We can design corresponding solve project according to our customers.
