HC1700 Grinding Mill is a newly developed large-scale roller mill by Guilin Hongcheng. The equipment referenced the operating principle of pendulum mill and improved the swinging method. Without changing other parameter, the centrifugal grinding pressure increased about 35 . The grinding area of roller and ring is improved, the output has 2.5.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.
The discs of an attrition mill are generally in a vertical position so that materials not capable of reduction can pass by gravity out of the grinding area. 2.3 Roller Mills. A combination of cutting, attrition, and crushing occurs in roller mills.The mill table, due to mill and roller’s relative movement, materials get into the grinding layer between the roller and the mill. In suspension between classifier and table, material drying transpires will takes place. The unstable grinding bed causes the VRM to vibrate. Water is directly sprayed into the bed to make dry mill feed, which is.
