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 To maintain a proper balance between these two is critical What water does is kind of provide a mode of ,
