Figure Cutaway view of the Hardinge conical ball mill showing how energy is proportioned to the work required is about kg/Mg of material for dry grinding, and kg/Mg for wet grinding. The normal charge of balls is about 5 Mg/m3. In small mills where very fine grinding is required, pebbles are often used in place of balls.
