— Plain Bearings & Rolling Bearings. The use of a long trunnion cannot be avoided if hydrodynamic plain bearings are to be used, since such mill bearings are usually designed with a width/diameter ratio of approximately 0.4. This is because the oil film thickness is heavily influenced by this ratio.

— 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.
