High Weir Type Spiral Classifier Introduction:
The high weir type spiral classifier is simple in structure, reliable in operation and easy to operate. There are four kinds of classifiers: high Weir single screw and double helix, sunken single screw and double helical classifier. It is widely used in concentrator and ball mill to form closed circuit circulating distributary ore sand, or in gravity concentrator to classify ore sand and fine mud, and in metal processing process for granularity classification of slurry and desilting in washing operation, Dehydration, etc.

Working Principle:
The high weir type 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.
