Spiral separator theory

Apr 30, 2020

Spiral Separator,Screw Classifier,Screw Classifiers ... The Working Principle of Spiral Separator: The screw classifier is relying on the different sizes, various specific gravity in order to reach the different theory of settling velocity in the liquid, which can cause the fine mineral particles floating in the water into over flow, and the coarse ore particles sinking into the bottom
