Enhance Resource Utilization Multi-Functional Spiral Sand Washer for Tailings Recovery Environmental Protection Policy Compliant

When the screw screen washing machine is in operation, the processed materials are first put into the sand washing device ofthe roller. After screening in the roller device, the qualified materials in the two kinds of materials with diferent particle sizes aredirectly transported through the conveyor belt, and the materials under the screen enter the middle water tank, After being cleanedand screened by the screw blade, the qualified materials enter the back end. Dehydration is performed in the dehydration plant. Theoverfow part of the wastewater in the tank (including a small amount of qualified material wastewater and impurities which have notbeen picked up by the spiral blade) enters the back-end pumping tank, and is pumped into the separation and recovery device bythe high-pressure water pump, and the qualified material is sent to the dewatering device for dewatering treatment after centrifugalconcentration. The waste water and impurities are discharged into the return water tank after separation and recovery device.
