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.

A comparative study on the effects of dry and wet

2019-9-1 · Chapman et al. (2013) compared the effects of using different circuits HPGR (dry) -rod mill (wet) and cone crusher (dry) -rod mill (wet) on the flotation of base metal sulfides. They indicated that apart from the grinding environment, HPGR could produce finer particles than a cone crusher. This difference was higher in the fully dry system.
