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 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 the large amount of sand and gravel de-sludge operations by hydropower, and it can also be used for washing, grading and dewatering sand.

The Screw sand washing machine utilizes the buoyancy action of water to separate dust and impurities from 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 in the bottom of the slope installation of water tank. The screw head sinks to the settling tank. The screw is rotating 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.

1) It can process materials within 0-30mm, and can wash the soil and ash powder on the material into clean materials.

2) The machine has the advantages of simple structure, easy maintenance and high washing efficiency.

3) The gravel is washed thoroughly and washed clean. The gravel rotates inside the spiral drum, and by washing the water stream, it can be said that all the mud adhered to the surface of the gravel is washed away. In this way, the mud content of the crushed stone is zero or only a few tenths of a percent, which ensures the strength of the box girder concrete and ensures the quality of the box girder and the construction progress.
