## Ball & Rod Mill Density – How Water Impacts Grinding

2018-11-22 · 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. To maintain a proper balance between these two is critical.
