Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the …

Referred to as the classifier or horizontal spiral classifier, the spiral classifier is one kind of equipment for the ore processing plant. It is the device for mechanical classification based on the principle that the specific gravity of a solid particle is different, therefore the rate at which it precipitates in a liquid also is different.
Details
The spiral classifier mainly rotates at a low speed by the spiral to stir the pulp to make the fine particles suspend to the top, flow to the overflow and overflow, and the coarse particles sink to the bottom of the tank, and are conveyed by the screw to the discharge port as returned sand. . ...
