Vertical Roller Mills (VRM) represent the most widely spread milling technology for raw materials in the cement industry and for many years also for clinker and slag grinding. The availability of a VRM largely depends on the driving gear unit which features the transmission between the motor and the VRM as well as the VRM axial thrust and radial bearings.

Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4.2H 2 O).
