Material Of Roll In High Pressure Grinding Roll

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface.

Finish-grinding The use of the high-pressure grinding roll for finish-grinding permits maximum energy sav-ings. In comparison with conventional ball mill grinding systems, up to 50 % of energy can be saved. Feed material with up to 6 % moisture content is dried in the separator. Material with higher moisture contents is dried in a separate

01-06-2005· 1. Introduction. High-pressure roll grinding has achieved considerable popularity over the last several years given its potential of improving capacity and reducing energy consumption in a grinding circuit (Schönert, 1988, Fuerstenau et al., 1995, Norgate and Weller, 1994).Comminution in the high-pressure grinding roll (HPGR) is the result of the high interparticle stresses generated when a ...

very sides of rolls the material breakage is lower than in the central area) are signifi-cant. Principles of high-pressure comminution The main part of the high-pressure grinding rolls press is a set of two counter-rotating rolls running in bearings and enclosed in the frame. One roll is settled in the frame in
