Fine Sand Recovery Machine

Fine Sand Recovery Machine

The fine sand recovery machine will inject the mud with a concentration of less than 40% into the hydraulic cyclone separator through the slurry pump for separation, and the separated coarse particles will enter the dewatering screen for recovery. The materials above 75cm can be recovered to a maximum extent, and the sludge and clay below 75cm can be removed. It can be used with the sand washing machine on the existing production line or can be used alone to improve the utilization rate of resources. Achieve greater benefits. Stable and reliable operation, good economic benefits.

Performance Feature

• Fine sand recovery machine can well solve the problem of high fineness modulus of finished sand and low stone powder content, reduce the rate of fine sand loss, can be controlled within 5%-10%, can recover 85% of the total amount of fine particle materials, with superior operation technology and performance.

• The dewatering screen of the fine sand recovery machine uses the polymer polyurethane screen. Compared with the screen of other materials, the life of the screen is longer, and there will be no plugging phenomenon. The cyclone is lined with ultra-high molecular polyurethane, the overall service life can be extended, and the slurry concentration and liquid clarification can be completed successfully.

• Fine particles are fully recovered, can greatly reduce the workload of the sedimentation tank, reduce the cleaning cost of the sedimentation tank, and do not need to stack these fine materials for a long time, can be directly transferred to the market; Equipment according to the national environmental protection standard design, low noise, but also supporting equipment dust removal, improve the working environment.

• The fine sand recovery machine can be moved to the designated position according to the production needs, which will save time and effort in the fine sand recovery and sand washing plant sludge wastewater; The equipment is simple to operate and easy to learn, and there is no need for too many operators in the operation process, which can save certain labor costs. Users can also choose and customize according to their needs.

Working Principle

The slurry sand water mixture is transported to the mud sand high-pressure separator, and the tail sand enriched by centrifugal classification is provided to the dehydration screen through the sand sedimentation nozzle. After dehydration through the dehydration screen, the tail sand and water are effectively separated, and a small amount of tail sand and mud are returned to the cleaning tank by the return tank. When the level of the cleaning tank is too high, it is discharged through the discharge port. Dehydration sieve recovery material weight concentration of 70%-85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar concentration, adjusting the overflow water and replacing the mortar nozzle. To complete the three functions of cleaning, dehydration and classification.
