Ball & Rod Mill Density How Water Impacts Grinding

2015-8-6 · Rod mill grinding efficiencies have been shown to increase in the range of 5 to 15% with more dilute discharge slurry (i.e., increased feed water) at least down to the range of 45 to 50% solids by volume. The higher the discharge % solids in the plant rod mill, the better the candidate for feed water addition rate test work.

INDICATION OF GRAIN ENLARGEMENT IN DRY

2005; Bai, 2005; Lekkas et al., 2014). Rod mill is a tumbling mill characterized by the use of rods as grinding media and frequently used in primary grinding (Gupta and Yan, 2006). The rod is more demanded than the ball due to its higher reduc-ibility. As a result, the grain size distribution can be more controlled (Sedarta et al., 2014).
