Aug 06, 2015· Ball & Rod Mill Density – How Water Impacts Grinding. Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods.

A rod mill has a reduced capa city when used for dry grinding. The material is hindered by the rods when passing from the feed end to the discharge area. Peripheral discharge is recommended. Due to the hindering effect that the ball charge gives to the material flow in dry grinding, the ball charge is not more than 28-35% of the mill volume.
