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.

A discussion on the measurement of grinding media wear

Laboratory mill tests can be an alternative to assess the wear of grinding media, as they can reproduce, at least partially, the conditions of an industrial ball mill.
