Spiral Classifier Structure
Spiral Classifier Working Principle
The grinded pulp is fed into a tank from the inlet in the middle of settlement region, and the slurry classification sedimentation area is under the inclined tank. The spiral with low-speed rotation stirs the slurry, so that the fine particles rise, and the coarse particles sink to the bottom of the tank. The overflow dam is above the bearing center which is under screw shaft, and is underneath overflow end.

Spiral Classifier Introduction
The spiral classifier is one of the size classifying equipment for the mining industry. It is a kind of equipment for mineral classification based on the principle that the specific gravity of solid particles is different and the speed of precipitation in the liquid is different. It can filter the material powder from the mill, then screw the coarse material into the mill inlet with the spiral slice, and discharge the filtered fine material from the overflow pipe. Spiral classifier short for the classifier. The classification machine mainly has the high weir type single screw and the double screw, the sinking type single screw and the double screw four kinds of classification machines. The classifier is mainly composed of a transmission device, a spiral body, a trough body, a lifting mechanism, a lower bearing (Bush) and a discharge valve. Spiral classifier is widely used in mineral processing plants with a ball mill as a closed-circuit circuit to separate the flow of ore sand, or used in gravity concentrator to grade ore sand and fine mud, and metal beneficiation processes to grade the size of ore pulp and washing operations in the desliming hopper, dehydration and other operations.
