Load Formula In Ball Mill

Rod Mill an overview ScienceDirect Topics

Rod mills are used in an open circuit between crushing and the ball mill They often operate in wet and where the pulp contains up to 50% solid by mass This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture As such when the product is sticky rod mills are preferred over ball mills
