1. Introduction. The vertical roller mill (VRM) is heavy mechanical equipment that used in the cement materials industry to process cement, slag, and coal cinder (Pani Mohanta, Citation 2015).The equipment always needs to work in the environment of heavy load, high temperature, high pressure, high corrosiveness, electromagnetic radiation interference, and multifield coupling, thus it is ...

ball mills for cement grinding, a 245 t/h vertical roller mill was added. The rating of the MVR mill of the type MVR 5000 R4 is based on grinding tests conducted at the test station of the Gebr. Pfeiffer SE in Germany. There are several pilot plants available with MPS and MVR mills which are operated in the same way as industrial plants.
