- Vertical Roller Mill for fine products - EcutecSummary. The VRM is a 3 roller air-swept mill design developed for continuous operation with a minimum of maintenance. The fundamental difference between the VRM and other tableroller mills is the bearing arrangement for the grinding table which is incorporated into the base of the mill. This enables an operation with.vrm differencebetween و آسیاب,process control for cement grinding in vertical roller mill (vrm)The success or failure of the VRM production depends on pressure difference between inlet and outlet, the grain size of the raw material [1, 2]. For VRM the production capacity denotes both the capacity of grinding and drying of mill. The grindability affects the capacity of grinding, type of mill and roller pressure. The capacity.
