The spiral sand washer has good structural layout and effective sealing design, which makes it durable without maintenance for a long time. Low water consumption and low working noise.The spiral sand washer has good structural layout and effective sealing design, which makes it durable without maintenance for a long time. Low water consumption and low working noise.

When working, driven by the screw, the sand and gravel grind each other to remove the impurities covering the surface of the sand and gravel, and at the same time destroy the water vapor layer covering the sand, and complete the cleaning and impurity removal function under the strong water flow. With the help of the principle that the size of the solid particles is different, the specific gravity is different, and the settling speed in the liquid is different, the fine ore particles float in the water to overflow, and the coarse ore particles sink to the bottom of the tank and are pushed up by the screw and discharged.
