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.

2019-7-12  Extensively sampling of the rod-mill discharge on line 18 with and without dry cobbing indicated that the rod-mill discharge was consistantly 1 to 2 percentage points low in magnetic iron content as compared with the feed samples. The feed samples agreed well with the plant magnetic iron analyses on the feed belt. Rapid
