Stuff with different specific gravity falls at different speed in fluid, by this principle and combined with grinders; spiral separator is used to eliminate dust and water in the mining material.
Guide for operation Of Spiral classifier(Screw Washer):
Before starting, firstly check the tightness of all the bolts, then raise the handle to make the machine work without load, after making the deposit move, the machine can work normally. The two ends of the bearing should be always maintained with lubricant.
