Ball mill - Wikipedia

The ball mill can grind ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type, due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.

Ball and 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
