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 grinding machine widely used in mineral processing to gradually decrease the size of ore particles. It is made of cylindrical drum supported by a frame. The inner part of a grinding mill contains horizontal bar knows as lifters to lift the charge. Ball mills
