Liming screw sand washing machine is mainly used for sand processing, electric pole factory, building work site and concrete dam, various sands classifying and dewatering. This sand washer adopts inclination of 15°, under the water tub, three weir plates form the sediment pool, the screw head is immersed in this pool, the screw is driven by electric motor through reducer rotating continuously, the fresh water is feeding from porous plate at bottom of sediment pool, this machine have three functions of washing, dewatering, classifying.

crushed stone, pebble stone, river stone,etc

Screw sand washing machine is used in Mining, quarry, and construction, industries for various sands or stone classifying and dewatering.

Screw sand washing machine is a machine which uses the buoyancy of water to separate dust and impurities from sand. With the agitation of the screw slice, the impurities will be washing off. Meanwhile, the fine sand and the coarse sand will be mixed uniformly while it is lifted up.
Screw sand washing machine is designed according to the characteristics that materials with different particle size and density have different settling velocity in the fluid. The particle with fine size and less density has a lower settling speed. Conversely, the particle with coarse size has a higher settling speed. With the agitation of the screw slice, you can get the purpose of separating dust and impurities from sand.
