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 ...

Critical Speed and a Grinding Ball. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.
