Spiral Classifier for Mineral Processing/Mineral Screw Classifier

Spiral Classifier is widely used to control material size from Ball Mill in the beneficiation process, separate mineral sand and fine mud in the gravity concentration, and clean mud and water in washing mineral process.  This machine has features of simple structure, reliable and convenient operation, etc.

Spiral classifier is a kind of classifying machine that classifies big and small mineral granules. It works according to the fact that different granules (with various sizes and weight) sink at different speeds in liquids. It can filter powders grinded from mill and rotate the coarse materials to the feeding hole of the mill and discharge filtered fine materials though the overflow pipe. The chassis of this spiral classifier is made of channel steel and the main machine is welded by armor plate. The water inlet and the shaft head come with cast iron sleeves, which are robust and abrasion resistant. Both manual-operated and automatic hoisting devices are available.

Features:
1.  Simple structure;
2.  Reliable working condition; 
3.  Convenient operation;
4.  Allows the fine ore to flow in the water.
