The Role of Classification in Grinding And Classifier …

The spiral classifier is divided into high weir type, submerged type, and low weir type according to the position of the spiral in the water tank and the height of the overflow surface. The high weir type is suitable for separating the overflow larger than the particle size, so it is mostly used for the first stage grinding.

Spiral Classifier, Dewatering Screw

This spiral classifier/dewatering screw is a multi-purpose machine. As a classifier, it separates out the smaller waste particles from the ore processor tailings. The larger particles can then be returned to the grinding circuit for finer grinding to liberate more values. Many locations don't have a ready source of water, so when used as a ...
