Spiral sand washer LSX920 is divided into two types: single-screw sand washer and double-screw sand washer, which are mainly used for washing, grading, impurity removal, fine-grained and coarse-grained material washing in highway, hydropower, construction and other industries.

Under the action of high-speed centrifugal force, the spiral sand washing machine collides and smashes at high speed with another part of the material that flows around the impeller in an umbrella shape.

After the materials collide with each other, a vortex is formed between the impeller and the casing They collide with each other and rub each other for many times to be crushed, and are discharged straight from the lower part to form a closed circuit for multiple cycles, which are controlled by the screening equipment to achieve the required particle size of the finished product.
