Spiral Classifier Introductions:

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.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.

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.
