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 ...

The other major repairs that take place on ball mills are to replace the liners and diaphragms and on a VRM to replace (or turn) the rollers and replace the table. The liners on a ball mill generally last up to 5 years in the first chamber and as long as 8 years in the second chamber and therefore are infrequently changed.

Ball Mills. In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
