The working principle of sand washing machine:
When the sand washer works, the motor drives the impeller to rotate slowly through the triangle belt, reducer and gear deceleration. The sand and stone feed trough enters the washing trough, rolls under the impeller's impeller's impeller's impeller's impeller's impeller's impeller's impeller, grinds each other, removes the impurities covering the surface of the sand and destroys the vapor layer covering the sand grains to facilitate dewatering. At the same time, the water is added to form a strong Take it away and drain it from the overflow flume to complete the cleaning function. Clean sand and gravel are taken away by the blades. Finally, the sand and gravel are poured into the discharge trough from the rotating impeller to complete the cleaning of the sand and gravel.
