Grinding operation. The cement vertical mill can quickly grind different raw materials into the required fineness. As the vertical mill uses a motor to drive the grinding disc to rotate the powder, not only the speed is high, but also the system is convenient, material enters the system from the feeding port, it is ground into a powder and outA cement Vertical Roller Mill modeling based on the number of breakages. It is used to grind slag, nonmetallic ore, and other block and granular raw materials into the fine powders necessary for production. In the mid-1990s, Loesche GmbH developed the VRM technology, which was first used for grinding clinker and slag [3].Loesche vertical roller mills for the comminution of ores and minerals
