Spiral Classifier

This machine is the main equipment in mineral dressing plants, for grading ore pulp size; it is also used for desliming, dewatering and other works in sand washing. It’s divided to single spiral and double spirals; according the difference of spiral’s depth in overflow surface, it’s divided to high weir type and sinking type.
