Sep 02, 2011· Both a macroscopic and a microscopic analysis of the wear parts has been conducted. A laboratory scale vertical roller mill with a transparent roller/table has been developed to further understand the material movements during grinding. The development of a simple wear test apparatus has verified the type of wear mechanism dominating the process.
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.

After the mill was in operation for over 10,000 hours the roller and table wear rates have been measured 2 times, once through each method. Described above, cement vertical grinding roller segment rotation and rewelding of both the table and roller liners. The actual wear rate for both the roller and table liners before hardfacing was g/T.

Improved performance with advanced wear materials in vertical roller mills. 1 Wear pattern of the rollers. 2 Starting to rebuild 10 cm from the edge. 3 Maximum 20 mmwear after 15 000 hoursof service.
Vertical Cement Mill: A vertical cement mill is used for the finishgrinding of cement. Its grinding table liners and roller sleeves are made from wearresistant hard facing material or ceramic material. Blades of the separator use highquality and wearresistant plates.
At regular intervals, therefore, the table and roller wear liners must be exchanged or repaired by surfacelayer welding. Without the natural redundancy of an approach with two mills in parallel, flexibility is key. The OK™ mill has individual roller arrangements with swingout mechanisms to facilitate maintenance or replacement of the rollers.
The highest wear occurs on the wear parts of the grinding elements as is the case with any type of vertical mill. 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.
