A Review of the Modeling of High Pressure Grinding Rolls

HPRM. Other designations were also used for the high pressure grinding technology with respect to a wide range of applications from coarse crushing to very fine grind-ing, such as 'high pressure roller crusher', HPRC. The ge - neric term that has been widely settled upon is HPGR, high pressure grinding rolls, and is used in this paper as well.

HPGR High Pressure Grinding Rolls |

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 ...

High pressure grinding rolls (HPGR) - Outotec

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 High Pressure Grinding Rolls

Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.
