- Autogenous and Semiautogenous mills - AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill. All because of the range of mill sizes available, AG/SAG milling extends itself to many appliions.
- Mill Speed as a Manipulated Variable for Ball Mill Afton claims that the variable mill speed has been useful for preventing liner wear while processing soft ore (Pazour, 1978). Sydvaranger processes iron ore through a 21 by 33-foot variable speed ball mill. The speed range of this mill is from 62 to 82 percent of critical, with normal operating speed at 78 percent.
