Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal

LM-Master mill optimiser Loesche has unique knowledge of all aspects of roller mill design, operation and automation, allowing the development of detailed and accurate mill control models. These have been incorporated into an advanced control software platform which allows the mill control functionality to be configured and held in-house to protect

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.

Therefore, ease of replacement and regeneration is a major feature of the mill. The MVR mill has a modern hydraulic system used in operation and for maintenance alike. With this new type of roller suspension, the rollers can be swung out of the mill in a controlled way – for ease of replacing the one-part grinding roller tires.
