Spiral sand washing machine/spiral sand washer  working principle:

Spiral sand washer /spiral sand washing machine is developed according to the principle of different particles with different fall velocities because of their sizes and densities. Fine particles float in the water and form the overflow; coarse particles fall down to the bottom of the trough and are pushed to the top port by the impellers and discharge. During working, the motor drives the impellers to rotate slowly by triangle belt, decelerating motor and gears. Sand enters the washing trough from the fed trough, roll and grind each other under the driving of impellers. Then wrapped impurity around the sand surface is removed and the vapor layer is destroyed at the same time. While the impurities and dirt is removed by the added water flow, cleaned material is conveyed upward by the rotating impellers to the discharge chute. xsd sand washing machine
