The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material, a protective coating of ground material covers the mill liners and grinding balls. It is known that cement raw material is much less abrasive than cement clinker.

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.
