Ball Mill. A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.

The ball mill has a low rotation speed, a large media size, and a large radial velocity gradient along the pin. Therefore, the grinding efficiency is lower and the particle size distribution is wide. Therefore, the ball mill is gradually be replaced by the bead mill, and is now only used for hard Alloy, ferrite grinding or pregrinding.
