  • Comparison of grinding characteristics in high-pressure ...

    2017-5-26  Comminution in HPGR is a result of high inter-particle stresses generated when a bed of solids are compressed while moving down the gap between two pressurized rolls. The priority that HPGR can generate fine products followed by grinding in ball milling, puts a competitive pressure on the application in semi-autogenous (SAG) mills.
