In a ball mill, the grinding process takes place by impact and attrition. On the other hand, a vertical roller mill exposes a bed of material to a pressure high enough to fracture the individual particles in the bed. This process creates a stable and consistent grinding bed between the rollers and the VRM table.

The grinding of the finished cement consumes approximately one third of the total electrical energy of a cement plant. Vertical roller mills (VRM) have a higher energy efficiency than ball mills, even if the ball mill is combined with a roller press. This and further arguments led to the increased share of VRM for the grinding of finished cement.
