grinding rollers and grinding track is relatively low. The thick-ness of the material bed between roller and table is a multiple of the particle size. Thanks to the integrated separator (classifier) the grounded material is separated after each passage. In comparison to a ball mill (with external separator), the separation is sharper.At Walzmühle, chilled cast-iron rolls were created in the local foundry for use in the roller mills. These rolls soon became the industry standard and were exported around the world through the 19th century. Some roller mills also used porcelain rollers, especially for processing semolina after stone grinding.Roller Mills: What They Are & Why They're Great Automatic

A study of operating parameters of a roller mill with a new
The mill is equipped with a hopper and a grinding product basket. The gaps between the rotating rollers and the friction plate are adjustable, depending on the nature of batch and requirements of the grinding product. Preferred gap sizes are modular roller mill design, the same grinding roller modules are used for both raw and cement mills, and parts commonality is achieved. Furthermore, by matching mill power and table rotation speed, identical reduction gear units are used on the three VRMs: one set of 5-roller raw mills, and two sets of 6-roller cement mills.Yasuhiro Shigemoto, Hirofumi Kasai and Tatsuya

Operational parameters affecting the vertical roller mill
In the air-swept mode, the vertical-roller-mill and a high efficiency dynamic classifier are suited above each other as a single unit (Fig. 1). Material is fed to the grinding chamber and transported by table rotation to the grinding gap between the fixed grinding rollers and the mill table. Crushing and grinding take place by compressive grinding.With many years of experience in technical innovation within the field of cement and slag grinding, CITIC Heavy Industries (CITIC HIC) has successfully developed various models of vertical roller mills.
