The mill speed and filling were varied, and the torque required to drive the mill and power was predicted. Mishra et al. conducted the motion analysis of particles in ball mills using DEM. The results predicted the motion of two arbitrary particles, charge profile similar to the laboratory ball mill.
With applications such as lime slaking or limestone grinding, smaller capacity ball mill systems are often required. In these instances, a cost effective option, when compared to larger trunnion mounted mills, is a roller mounted ball mill. This design uses heavy duty support rollers to drive the rotation of the mill shell directly.
Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing the ball charge. Seal the mill. Rotate for 20 revolutions to clean. Empty the mill charge and sand into the ball try once grinding is complete. Clean out the mill using a brush. Put the lid on the mill.

Such mills are common in South African operations; mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90% of critical speed) and often use "grid" liners to form an autogenous liner surface.
