Brief Introduction:
screw stone washer is mainly applied to washing minerals of large slit content, such as iron, manganese, limestone, tin ore, etc. It carries out mixing, washing, separating, and desliming. with a washing pressure less than 147-196kpa, it is also suitable for washing building materials in construction and power station applications. The gear transmission parts of our spiral washing machine are separated from stones, water and sands, which greatly reduces the error rate of our spiral washing machine. 

Features: 
1. This sand washer is of simple structure. The driving device of the impeller is separated from water dirt and sand. This greatly reduces the fault rate. 
2. Compared with traditional spiral sand washing machine, this sand washing machine has the following merits. 
This machine causes little loss of fine aggregate and sand. It complies with national standards listed in Sand for Building Usage and Cobble and Aggregate for Building Usage. 
This machine has almost no wearing parts except screen cloth. 
This sand washer enjoys long service life and free maintenance.

Working Principle
Spiral washing machine makes use of buoyancy of water to separate sand from dust and impurity. It achieves purifying, lifting and conveying of the minerals through the stirring of spiral slice. During lifting, the minerals are also stirred so that the coarse sands and fine sands are evenly mixed.
