  • 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

  • Introduction of High Pressure Grinding Roll Luoyang Dahua

    Working principle of high pressure grinding roll: the grinding roll is composed of two extruding rollers, one is fixed roll and the other is movable roll. The material is continuously brought into the roll by the extrusion roller, and after being subjected to high pressure, the material forms compacted and is removed from the machine.
