mineral grading machine 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. Spiral classifier 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.
