Crushing in a HPGR Feed Product. Amenability of different ore type to HPGR? Key questions Throughput (t/h) Ore competency cost Morley (2006) Testing Quantification of HPGR benefits Does an open circuit HPGR do a better job than a modern closed circuit cone crusher for tertiary crushing duties? Does HPGR technology provide lower energy and steel consumption? Does HPGR

Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce 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 volume, exceeding its compressive strength with equal pressure being applied to
