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, and stainless steel balls.

Ball mills of greater length are termed "tube mills," and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as "pebble mills.'' In general, ball mills can be operated either wet or dry and are capable of …

Displacement of balls in mill. n = 42.3 D m where D m is the mill diameter in meters. The optimum rotational speed is usually set at 65–80% of the critical speed. These data are approximate and may not be valid for metal particles that tend to agglomerate by welding. The minimal magnitude of ball size is calculated in millimeters from the equation:

L = Mill length in meters. Ï B = Ball density in t/m 3. Wet Ball Mill Power Draw (Bond) For wet ball mills, Bond expressed power draw as a function of the total mass of media:Pâ†"M / Mâ†"B – 15.6Î¦â†"V (1 – 0.937 Jâ†"B) Dâ†'0.3 (1 – 0.1 / 2â†'9 – 10Î¦â†"C) kW/t
