  • High pressure grinding rolls (HPGR) minevik

    High pressure grinding rolls (HPGR) are used for particle reduction in mining operations and aggregates production Known for energy efficient reduction, HPGRs are most often utilized when the processed material is hard rock However, they can also refine softer materials like industrial minerals The smaller models of the HPGRs are particularly productive in producing manufactured sand forHPGR technology is a qualified alternative for largescale comminution circuits and is becoming ever more popular in minerals processing The technology's working principle is that two counterrotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls Interparticle comminution is the HPGR specific grinding process in which material particlesHigh Pressure Grinding Rolls (HPGR) | TENOVA

  • Roller press HPGR technology solutions |

    Roller press machines for pregrinding, semifinish & finish grinding For extreme efficiency and high equipment availability, look no further than roller press technology and products from The roller press is a uniquely designed comminution tool, in that feed ore is exposed to extremely high pressure for a short amount of time resulting in a highly effective method of size reductionUsed 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 particlesHPGR High Pressure Grinding Rolls | Weir
