New Improved Best Performance Mineral Processing Screw Classifier/mining Spiral Classifier Machine
Description of spiral classifier
Classifier machine is widely applied to the concentrating mill and make up closed circuits process with ball mills to separate mineral sand, or in the gravity concentrating mill to classify ore sand and mud, and in the metal process to classify particle size for ore pulp, as well as desliming, dehydration, etc. job in washing operation, dehydration and other operations, the classifier is of simple structure , reliable working, and easy operation etc. characteristics.
Working principle of spiral classifier
Spiral Classifier by means of the theory of different solid particles sizes, different specific gravity, thus settling velocity of the liquid is different, fine mineral particles floating in the water and overflow ,coarse mineral particles sinking to bottom , into the upper by screw and discharge, is a classifier equipment to classify , able to filter feed powder grinded from grinding mill , and then using a spiral piece screw the coarse material into the feed inlet of mill , to filter out the fine material discharged from the overflow tube. The machine base is made of channel steel, body is welded by steel plate.
The Structure of spiral classifier Spiral Classifier is mainly equipment by transmission, spirochetes, tank, lifting mechanism, lower seat (bush) and valve gate , hoisting plant include power operation and manual operation two parts.
