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 strength with equal pressure being applied to particles of all

High Pressure Grinding Rolls (HPGR) TAKRAF GmbH

High Pressure Grinding Rolls (HPGR) HPGRs are modern and efficient comminution machines, which are becoming increasingly popular within the minerals processing space. HPGR technology as an alternative to crushers and mills HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming increasingly popular.
