Working principle
Working principle

The spiral sand washing machine is composed of a weir plate, a casing, a spiral body, a reducer, and a motor. When the spiral sand washing machine is working, the motor can be controlled to make the screw device rotate continuously. 

Clearwater enters the body from the perforated plate at the bottom, and the material is fully mixed with water from the feeding part to the discharging part. Under the action of the screw device, the water can effectively remove dust and impurities on the surface of the material. Then the finished product is discharged through the discharge port, and the mud and impurities are discharged through the overflow port to complete the cleaning.
