The screw sand washer is the professional sand washing machine developed on the basis of previous technology and combined with the actual situation of sand and gravel industry. It is a high-efficiency sand washer which can separate the excess powder and mud and so on in the raw material. When working, the sand will grind each other under the driving of the impellers. By this way it can not only remove the impurities wrapped on the surface of the sand, nut also destroy the vapor layer wrapped around the sand, and completes the impurity cleaning processing in powerful water flow.


1.Three functions: cleaning, dewatering and grading.

2. Cleaning and upward conveying at the same time.

3. Low water consumption; durable.

4. Impellers use wear resisting plate or polyurethane material, reduce the running cost.

5. Designed according to low volume, low investment.

6. Capacity of screw sand washer is above 100t/H, effectively control the sand washing loss.


Spiral sand washing machine is mainly used for sand factory, electric pole factory, work-site of building and concrete dam to wash, classifying and de-watering various sands. This sand washer adopt 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, de-watering, classifying.

Working principle:

The sand is feeding into the sediment pool from the feeding box, acting by rotating screw blade, the sand is turning and rolling and grinding each other to eliminate impurity and water-air layer around sand to facilitate dewater. The fresh eater rising current from the porous plate carry foreign matter to water surface and overflow the weir plate, to finish washing processing. Dewatering: The sand with bigger density is sunken down to tub bottom, the screw blade push this sand upwards, when passing through upper tub of proper length above water level, the water is draining into sediment pool from another drainage ditch, the de-watered sand is out from the discharging opening. Classifying Material classifying is realized by overflowing the non-needed fines, the controlling method is adjusting height of overflowing weir and adjusting speed of screw.
