A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles

If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods, secondary ball mill with 25—40 mm(1″—1½”) balls and possibly tertiary ball mill with 20 mm (¾”) balls or cylpebs. To obtain a close size distribution in the fine range the specific surface of the grinding media should be as high as possible. Thus

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Small Ball mills generally operate at slightly higher speeds than rod mills and thereby impart a cascading action to the grinding media. Small Ball mills are generally recommended not only for single stage fine grinding but also have wide application in regrind work. The Small Ball mill with its low pulp level is especially adapted to single

Mills in which the mechanism operates at moderate speeds (medium-speed mills) are used for dry grinding of soft and moderately hard materials (coals, cement raw material, phosphorites, graphite, sulfur, talc, and mineral paints). Medium-speed mills may be of the roller, roll, ring, friction-and-ball, or crusher-roll types. The main patents for medium-speed mills of various types date to the

In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables. Mill Speed is one variable that can often be easily changed with a variable frequency
