  • High Pressure Grinding Rolls (HPGR) | Mining | SGS

    HPGR have been used for many years and are emerging as an energy-efficient alternative to conventional and AG/SAG comminution circuits. One of the interesting features of HPGR is its capability to produce a particle size distribution with a greater than typical amount of fines, thus reducing the power requirement for the downstream ball mill.
