Spiral Classifier

Spiral classifier is one of beneficiation equipment, based on user requirements, it can be divided into single and double spiral classifier. Depend on specific gravity of solid particles, so different sedimentation velocity in a liquid principle, spiral classifier is a mechanical grading equipment. Feed mill can grind the powder level in the filter, and then use the coarse material spiral piece rotary vane screwed mill feeder to filter out fine material discharged from the overflow tube.

When working, the spiral classifier relies on the principle that the solid particles have different sizes and specific gravity, so the sedimentation speed in the liquid is different. The fine ore particles float in the water and overflow, and the coarse ore particles sink to the bottom of the tank. It is a kind of grading equipment that is pushed to the upper part by the screw to carry out mechanical grading. It can classify and filter the powder ground in the mill, and then use the spiral blade to screw the coarse material into the feed port of the mill, and discharge the filtered fine material from the overflow pipe.
