Rod Mill - an overview ScienceDirect Topics

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill.

iron ore grinding rod mill working principle

Ore Grinding Mills are used for the fine grinding as the balls concentrate near the feed end of the mill where the coarsest ore collects and the smaller balls act on the finer ore. Rod Mills. Rod mills (see Fig. 17) follow the general dimensions of tube mills with diameters from 3 to 6 ft. and lengths from two to three times their diameter.
