Ball & Rod Mill Density - How Water Impacts Grinding
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.

C O N S U L T I N G L T D TECHNICAL MEMORANDUM
devices is (largely) reflective of the efficiency of the grinding device. Once the specific energy is determined, the amount of grinding power needed (at the mill shell) is found by mul- tiplying the specific energy by the desired throughput. Then a motor size and mill geometry is chosen that will satisfy the power demand at the mill shell.
