The VRM is a type of grinding mill that uses a vertically oriented, multilevel cylindrical roller to grind materials into extremely fine powders. The key components of a VRM are the grinding rollers and the grinding table. The grinding rollers are hydraulically loaded and held against the grinding table by means of hydraulic cylinders.
