HPGR High Pressure Grinding Rolls Weir

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 ...

High Pressure Grinding Rolls - 911 Metallurgist

28-07-2020  High-pressure grinding rolls were first applied in the minerals industry in 1985 in cement plants. The main objective for the use of HPGR was the significant energy savings achievable. Today, they are also being used by diamond mines and for the communition of coal as well as for the grinding of slag, iron and chromium concentrates (Figure 4).
