Spiral Classifier for Fine Ore Separation
Spiral classifier is widely used to control material size from ball mill in the beneficiatio process, separate mineral sand and fine mud in the gravity concentration, and clean mud and water in washing mineral process. Spiral classifier has features of simple structure, stable performance and easy operation, etc.
Working principle:
Spiral classfier is a kind of classfying machine that classfies big and small mineral granules. It works based on the fact that different granules(with various size and weight) sink at different speed in liquid. It can filter powders grinded from mill and rotate the coarse materials to feeding hole of the mill and discharge filtered fine materials through the overflow pipe. The chassis of the 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 sleeve, which are robust and abrasion resistant. The equipment is available both in manual and auto mode.
