A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.

In both cases, particle-size reduction occurs by collision of particles with the surfaces of the equipment as well as with each other. The collision events involve compression, impact and attrition, and cutting or shear as the main mechanisms for particle-size reduction (Clement and Purutyan 2002; Friedrich 2001; Spencer and Dalder 1997).
