Vertical roller mill Application process Raw material process Background In the vertical roller mill which is widely used in the raw material grinding process, raw materials input grinding table are crushed and pulverized on it and transported to separator by kiln exit gas introduced into the mill as drying, transporting and separating purpose.Each grinding roller is supported separately, and the door on the housing can be opened during the overhaul. The grinding rollers can be easily turned out of the grinding mill by means of the vertical mill hydraulic cylinder, and for overhaul and maintenance, the roller.
Grinding table is one of the key parts of the vertical roller mill. It is mainly composed of table body, liner plate, pressure block, retaining ring, scraper plate, wind ring, wind deflector and other components.Vertical Cement Mill A vertical cement mill is used for the finish grinding of cement. Its grinding table liners and roller sleeves are made from wear resistant hard facing material or ceramic material. Blades of the separator use high quality and wear resistant plates. Analysis and repair of wear in vertical grinding_cement.
The advantages of the vertical roller mill include a high level of grinding efficiency combined with reduced energy consumption. For raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product.1. Wear of liners of grinding roller and grinding table. When the vertical grinding mill works, the grinding pressure is exerted by the grinding roller, and the material is pressed and sheared by the grinding roller and the grinding plate to achieve the purpose of grinding the material. Therefore, the wear of the roller surface and the lining.

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 0.30 g T. The measured wear rate with hardfaced liners was 0.12 g T.AWM Table Roller Mill. The product is subjected to compressive stress between the grinding table and the grinding rollers. The specific grinding force (contact force divided by the cross sectional area of the grinding roller) is in the range between approx. 0.5 and 1 N mm , whereby the effective pressures in the material bed are naturally much higher.
Wear liners The wear liners of the grinding table and the rollers are of the seg mented type and are therefore easy to replace when worn out. For mills grinding very abrasive materials, such as slag, hard facing is a viable means of achieving a high availability of the grinding system, optimising the grinding process and saving refurbishment costs.Vertical roller mills Vs ball mills has long been a raging debate in the cement industry.
