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 feeds density to 80 of its solid volume, exceeding its compressive strength with equal pressure being applied to particles of all
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.
Jul 28, 2020 High-pressure grinding rolls HPGRs have struggled for acceptance into the hard-rock mining sector. CRITICAL HPGR PARAMETERS. HPGR roll diameters typically range from 0.5 m to 2.8 m, depending on the supplies, and roll widths vary from 0.2 m to 1.8 m. The aspect ratio of the rolls also varies as a function of manufacturer.
Jun 26, 2019 High pressure grinding roll is designed according to the principle of inter-particle breakage by huge pressures. The pressure is from a pair of counter-rotating rolls with the same diameter and rotary speed. One is fixed while the other is allowed to shift front and back slightly.
