    Improved Cost-Efficiency High-pressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing industry. The technology has found its key application in the liberation of diamonds and also in primary comminution. Compared with conventional grinding, the HPGR process consumes significantly less energy, which in turn leads to a reduction in

  • HPGR High Pressure Grinding Rolls

    HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

    The total power for the HPGR system can be compared to that of a conventional circuit, based on the rod and ball mill work indices and the Third Theory of comminution. The power comparison can also be done against AG/SAG mills. This methodology has only been used to scope the potential energy savings of HPGR at small scales.
