SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and ...

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

To improve ball mills the discrete element method is an optimal method due to the possibility of tracking the grinding media and their collisions. Cleary (1998) used the DEM to simulate the particle flow inside an autogenous ball mill for varying particle sizes and densities while interacting with complex geometries.
