As an energy-saving alternative to the SAG mill, HPGR is particularly suited for the pregrinding of hard, highly siliceous gold ores. This will help to downsize the ball mill while maintaining the throughput. In the pregrinding mode, HPGR use may result in energy savings of 15 to 30% and throughput increases of 20 to 40% (Schonert, 1991).

to enhance grinding productivity of the HPGR. — High pressure grinding rolls in mineral processing Moving from cement to hard rock High pressure grinding rolls (HPGRs), also known as roller presses, are rapidly gaining acceptance in hard-rock processing, primarily due to their energy efficiency when reducing mineral ore to fragments.
The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed's density to 80% of its solid […]
