HPGR High Pressure Grinding Rolls | Weir
What is 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,

High Pressure Grinding is applied in iron ore pellet feed preparation to generate a specific surface area increase. The technology is applied for final grinding of fine concentrates or pre-grinding (ahead of conventional milling) of particles.
Aspects of HPGR in Iron Ore Pellet Feed Preparation,
High Pressure Grinding is applied in iron ore pellet feed preparation to generate a specific surface area increase. The technology is applied for final grinding of fine concentrates or pre-grinding (ahead of conventional milling) of particles. The process assumes inter-particle breakage and inter-particle abrasion as a major factor in generation of fines which contribute
