A vibration mill typically consists of a cylindrical chamber, which contains grinding media such as balls, rods, or cylpebs. The chamber is vibrated at high frequencies, usually in the range of 1000-2000 Hz, by an eccentric motor or an electromagnetic drive. As the chamber vibrates, the grinding media collides with the material, creating ...
