The pump sends the sand-water mixture to the mud-sand high-pressure separator.The fine sand is collected by the centrifugal force of cyclone, then fed to the polyurethane screen from the apex spray. The 0.16-3mm fine sand and water are efficiently separated through the vibration screen. The waste water will flow back to the return box, through weld chute or pipes flowing to a settling pond.

1.Recycling 0.16-3mm fine sand.
2. Recycling rate reaches above 95%.
3. The water content of final sand is within 12%-15%.
4.Sediment separator uses high wear-resistant raw materials, high elasticity, high strength, high wear resistance, tear resistance, cutting and other characteristics.
5.The vacuum high-pressure pump adopts the latest vacuum high-pressure pump, which has the power to reduce pressure and seal efficiently, and the slurry is not easy to leak.
