Under the water tub, three weir plates form the sediment pool. The spiral head is immersed in this pool, and the spiral is driven by electric motor through reducer rotating continuously. The fresh water is feeded from porous plate at bottom of sediment pool, and the washed sand is discharged on the top side and delivered by belt conveyor.

2. Cleaning and upward conveying at the same time.
3. Low water consumption.
4. Impellers use wear resisting plate or polyurethane material so as to reduce the running cost.
5. Designed according to low volume and low investment.
