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. · HPGR has been found to be efficient size reduction equipment compared to conventional size reduction equipments due to its potential processing benefits in terms of energy savings, improved exposure or liberation and particle weakening. The objective of the current work is to study the optimization of different process parameters during grinding.
