The good structural layout and effective sealing design of the machine make it durable without maintenance for a long time. Low water consumption and low noise.

Under the drive of the screw, the sand and stone grind each other to remove the impurities covering the surface of the sand and stone, and destroy the water vapor layer covering the sand particles, and complete the cleaning and impurity removal function under the strong water flow. With the help of the principle that the settling velocity in the liquid is different due to the different size and specific gravity of solid particles, the fine ore particles float in the water and flow out, while the coarse particles settle at the bottom of the tank and are discharged from the upper part by the spiral.

Multiple effects, high cleanliness. The machine has the functions of cleaning, dewatering and grading. When working, the sand and gravel grind each other to remove the impurities covering the surface of sand and stone, and destroy the water vapor layer covering the sand particles, and complete the cleaning and impurity removal function under the strong water flow.

Wide range of application: it is suitable for washing, grading and removing impurities in metallurgy, building materials, hydropower and other industries. It is suitable for fine and medium grained materials, especially for construction sand and road construction sand.

High processing capacity and long service life. The output of the machine is as high as 350 t / h, and the cleaning and lifting conveying can be carried out at the same time.
