This series of products can clean and separate the soil in the sand and stone, and achieve the purpose of filtering water to remove impurities and lifting transportation under the uniform agitation of the spiral plate.  It has the characteristics of long spiral body, thick spiral sheet, rigorous sealing system, large processing capacity, low sand water content, no powder, no mud, less maintenance and so on.  Widely used in highway, water and electricity, construction and other industries of washing, grading, miscellaneous removal, as well as fine and coarse particle size material washing and other operations, especially suitable for construction and road construction sand and stone.  

The spiral sand and stone washing machine has reasonable structure, convenient maintenance, large processing capacity, low power consumption and high degree of washing. The novel sealing structure, fully enclosed oil bath type transmission device, and adjustable overflow weir plate ensure the high efficiency, durability, good cleaning and dehydration effect of this series of products, and the stability of fine-grained products.

When working, the power device reduces the speed of the impeller through the V-belt, reducer and gear, and then the impeller rotates slowly. The clean gravel is taken away by the blades, and then the gravel is poured from the rotating impeller into the discharge trough to complete the cleaning of the gravel.
