The Screw sand washing machine utilizes the buoyancy action of water to separate dust and impurities from the sand. It through the agitation of the screw blades, the purpose of filtering water is removing impurities. The screw sand washing machine a settling tank at the bottom of the slope installation of the water tank. The screw head sinks to the settling tank. The screw is rotated by the motor through the reducer driven, and the cleaning water is supplied from the bottom of the settling tank to complete the cleaning, dehydration, and classification. The machine rotor adopts a central structure, and the spiral blade is mounted on the central shaft and is connected to the central shaft by the reducer for work. An apparatus for mechanical grading by virtue of the fact that the specific gravity of the solid particles is different and thus the rate of sedimentation in the liquid is different.



The screw sand washing machine uses different particle size and density of particles to have different sedimentation speeds in the fluid. The particles with fine particle size and small density have a slow sedimentation rate, while the particles with large particle size and high density have a fast sedimentation speed, and the dust and The impurities are separated from the sand, and under the uniform agitation of the spiral, the purpose of filtering the water to remove impurities and lifting the transportation is achieved. The spiral sand washing machine has the advantages of a long spiral body, good sealing system, simple structure, strong processing capacity, convenient maintenance, and high washing rate. The spiral sand washing machine is widely used in highways, railways, municipal construction, stone factories, construction sites, concrete prefabrication yards. And a large amount of sand and gravel de-sludge operations by hydropower, and it can also be used for washing, grading and dewatering sand.
