high pressure roll crusher

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. Theycompress 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 | Weir
    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 gapbetween 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 …

    Theroll crushermodel was previously developed by Austin et al. (1980). It should be noted that grinding inroll crushersis completely different from HPGR grinding. Inroll crushers, the gap is fixed and no compressivepressureis applied to the rolls. Hence, breakage occurs through contact with the rolls.
