Overview

Spiral ClassifierIntroductions:
The spiral classifier is one of the equipments for mineral processing. The screw classifier is a kind of equipment for mechanical classification based on the principle of different density of solid particles and different settling speed in liquid.The grinding powder in the mill can be filtered, then the coarse material can be rotated into the mill inlet by spiral slice, and the fine material can be removed from the overflow pipe.Spiral classifier for short.There are four kinds of classifier: high Weir single screw and double helix, sunken single screw and double helix. The classifier mainly consists of transmission, helix, tank, lifting mechanism, lower bearing (bearing) and drainage valve. The spiral classifier is widely used in classifying ore sand and fine mud in concentrator and ball mill, or in gravity concentrator for granularity classification of slurry. Desliming, dehydration and other operations in ore washing operations.

Spiral Classifier Working Principle:
Spiral classifier is based on the principle of different solid particle size and different specific gravity, so the settling velocity in liquid is different. Fine ore particles float in water and overflow, and coarse ore particles sink at the bottom of trough.A classification device for mechanical classification by propelling the screw to the upper part of the mill, which can filter the grinding powder in the mill, and then swirl the coarse material into the feed inlet of the mill, and discharge the filtered fine material from the overflow pipe.The base of the machine adopts channel steel and the body is welded by steel plate. Screw shaft head, pig iron sleeve, wear-resistant and durable, lifting device divided into electric and manual two types.
Spiral Classifier
Spiral ClassifierFeatures:
1).Spiral classifier is Simple structure, reliable running and easy operation.
2).It mechanically classifies through the mechanism of different sedimentation speed of solid particle in liquid due to different size and different specific gravity.
3).It can classify the ground material powder from the grinder, spiral the coarse grain into material inlet of grinder through the spiral chip, and discharge the classified fine grain from overflow surface.
4).Its base is made from channel steel, and its body is welded from steel plate.
5).The lower support of spiral bearing is of engine-bearing structure of good wear resistance and durability.
6).The spiral classifier lifting device is of electric and manual mode.
