How XSD sand washing machine works

The electric motor runs slowly with the impellor after being decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing tank from feeding launder, rolls with the impellor, and grinds each other. The impurity covering the sand is washing away. The clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back in the washing launder. On one hand, water is removed from the sand and stone; on the other hand, the water can be fully used. Finally, the sand and stone go out launder from the rotary impellor to finish the washing task.
