Ballmill- Wikipedia

Aballmill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ballmillsrotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used asmedia, including ceramicballs, flint pebbles and stainless steelballs.
