Sand washer has many outstanding features such as simple structure, stable operation, high washing degree and high outputso that it is widely used in many industrial departments such as building site, sand and stone plant, glass plant, power plant and concrete sand making. When sand washer works, the power plant drives the impeller to slowly rotate after slowing down through the V-shaped belt, reducer and gear, and sand and stone materials go into the washing chute from the material cabin, and roll driven by the impeller and grind with each other to remove the impurities covering the surface of the sand and stone materials, and at the same time break the moisture layer coated on the sand particles for the purpose of dehydration. In the meantime, add water in it to form a strong water flow to timely wash away the impurities and foreign matters with small proportion and discharge them from the overflow port to complete the washing process.
