HPGR High Pressure Grinding Rolls

14/07/2016  Primary grinding in the high-pressure grinding roll increases the capacity of an existing dry ball mill operation. Even greater increases in capacity can be achieved if the Polycom is operated in hybrid mode. Hybrid grinding means that a part of the separator tailings (which are recirculated to the ball mill) is diverted and fed to the Polycom together with the fresh feed. Thus, some of the ...

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.
