Working Principle of Wheel Sand Washer

During work, the motor drives the impeller to rotate slowly after deceleration through the V-belt, reducer, and gear. The sand and stone enter the washing tank through the feeding tank, roll under the drive of the impeller, and grind each other to remove the impurities covering the surface of the sand and stone.

At the same time, the water vapor layer covering the sand particles is destroyed to facilitate dehydration. At the same time, water is in addition to form a powerful water stream, and impurities and small foreign objects with slight specific gravity are taken away in time, and discharged from the overflow tank to complete the cleaning effect.

Clean sand and gravel are made away from the blades, and the sand and gravel are poured into the discharge trough from the rotating impeller to complete the cleaning of the sand and gravel.

Working Principle of Screw Sand Washer

Screw sand washer is composed of a tank body, a spiral blade, a reducer, a central shaft, a motor and a bracket. The rotor of the machine adopts a fundamental structure, and the spiral blades are installed on the inner shaft. Reducer works by connecting to the central shaft.

When working, material enters through the inlet, and the gravel is screened and classified under the action of the spiral device by the specific gravity of the solid particles, and discharged from the discharge port.
