The mill roller is driven by the electrical motor through an electrical motor and the material will be fed to the center of the disk from the feeding port via an air-locking feeder and meanwhile the hot-blast air will be blown
Vertical Roller Mills (VRMs) are where the return on investment really comes into play. The mills are a primary cost consideration and once they are running, it is vital that they generate the best returns over time. PRODUCT RANGE MON0-METAL High Chromium (HiCr) alloy solution providing HIGH WEAR RESISTANCE for
Vertical Roller Mill (VRM) The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor
