There are two typed of …

Tumbling mills (ball mills, rod mills, etc.) utilize both continuous-pressure and impact mechanisms. Blasting, explosive shattering, and decrepitation (fire-setting) are tension-type crushing operations; all three are relatively unimportant as crushing operations, although blasting is, of course, pre-eminently useful in rock excavation.

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.
