Ball Mill

Ball mills are often operated at higher speeds than rod mills, so that the larger balls cataract and impact on the ore particles. The work input to a mill increases in proportion to the speed, and ball mills are run at as high a speed as is possible without centrifuging. Normally this is 70–80% of the critical speed.

Variables in Ball Mill Operation

In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.
