This machine can be used in metallurgy,build material,water and electrioitym,it is adapting to make big and small sand - details see: https://www.machineto.com/effective-screw-stone-washer-concreting-materials-10321327

Spiral washing machineis 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 ourspiral
washing machineare separated from stones, water and sands, which greatly
reduces the error rate of our spiral washing machine.

Working Principle:
Spiral washing machinemakes 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.

Features:
Spiral washing machinehas features like long spiral structure, good sealing
system, simple structure, strong processing capability, convenient maintenance,
good washing efficiency, etc. It is widely used in mining industry.
