A vertical roller mill has grinding rollers which roll over a grinding path of a rotatable grinding table, and a surrounding nozzle ring separation area for conveying and separating gas. A coarse fraction of ground material is entrained in gas upwards in ducts from a location that is below, at, or above the nozzle ring separation area and is transported into an entry to a material separator

Vertical Roller Mill Maintenance and Repair. Vertical roller mills became increasingly dominant for grinding raw materials mainly for the cement industry due to their high energy efficiency and excellent drying capacity. Maintenance and repair of vertical roller mill is a highly technical and specialized business, which should be performed by experts.

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.

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.

Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque ,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.

outlet of the mill (∆P mill) is an important process variable for the testing of grinding aids. ∆P mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ∆P mill indicates more internal circulations and more fines. As a re-sult of the higher ∆P mill, the mill vibration increases

wear liners in vertical roller mills (VRMs) is to reweld or hard face the worn surface. This means regularly stopping the mill. Because the wear rate in a VRM varies, depending on feed materials and product fineness, the number of times maintenance is required over a given time period is variable.
