Ball mills find applications across many disciplines, from materials research to chemical analysis and even biological research [78,79,80]. Ball milling is a process that utilizes mechanical forces, such as those generated by the rotating jar of a ball mill, to break up the material into smaller pieces and mix them together .

The test enables basic grinding power requirement in ball mills to be determined, from the feed 80% passing size (F80) to circuit 80% passing size (P80), using the classic Bond formula. The rod mill work index test requires 20 kg of material, which is crushed to mm (1/2) and tested in a standard Bond Rod mill.

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.
