Ball Mill Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. it works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell.

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.
