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 steelballs. An internal cascading effect reduces the material to a fine powder. Industrial ball mills can operate continuously, fed at one end and discharged at the other e

How does ball mill rotating speed influence grinding ...

On the contrary, if the ball mill rotating speed is too high, due to the centrifugal force, ores and grinding media will no longer out of the inner wall but rotating with the cylinder. Under this condition, grinding media will not create any impact force and grinding efficiency will be very low.
