What Factors will Affect the Process Effect of Spiral Classifier?

There are four types of classifiers, high weir type single and double spiral classifier, immersed single and double spiral classifier. Spiral classifier is also known as screw classifier and widely used for distributing ore in the close circuit with ball mill, grading ore and fine slit in the gravity mill and grading granularity in the flow of metal ore-dressing etc. It is the necessary equipment, so what factors will affect the process effect of spiral classifier?

1. Nature of the Mineral

Nature of the mineral is often refers to mineral density and particle size composition. Mineral density directly affects the production capacity of spiral classifier, and the greater mineral density, the production capacity of spiral classifier is higher. Mineral particle size composition affect the viscosity of the slurry. The viscosity increases, the settling velocity of mineral particles will slow down. And spiral classifier processing capability and classification accuracy will be reduced.

2. Structure of spiral classifier

The liquid surface area of mineral particles setting affects spiral classifier processing capacity. The larger area, the processing capacity is greater. And the size of area depends on the width of classification groove and the inclination angle of the tank.

3. Mineral Concentration

Mineral concentration will not only affect the classification particle size, but also processing capacity. Staff can control classification granularity by adjusting the mineral concentration.
