Oct 23, 2015· Thus, rollers are in permanent contact with the grinding bed. A hydropneumatic arrangement transfers the grinding pressure to the rollers. The disintegrated mill feed is shifted to the grinding bowl rim from where a gas stream emerging from the nozzle ring surrounding the grinding bowl carries the material upwards to the separator.

The grinding bowl is locked securely by a cam lever system, and a protective cover encloses the grinding chamber for safe and quiet operation. Wet or dry samples of 0.5in (12.7mm) maximum feed size are rapidly reduced to a final particle size of 150—38µm (No. 100 to No. 400 U.S. Standard sieve size), depending on the material.
Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012). Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used.
