### Ball mill - Wikipedia

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.

Jul 31, 2014 · Mill power draw prediction can be carried out using Morrell’s power model for tumbling mills (Morrell, 1998). Bond method The established technique for determining power requirements for ball mills is the Bond method (Bond, 1961). This method also involves the application of some ‘efficiency factors’ as described by Rowland (1975).
