hpgr vs sag mill

The total power for theHPGRsystem can be compared to that of a conventional circuit, based on the rod and ballmillwork 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 ofHPGRat small scales.

    How HPGRs compare to conventional milling

    Aug 20, 2019· Within comminution circuits,High Pressure Grinding Rolls(HPGR) are increasingly replacing conventional SAG, rod and ball mills forhard rock reduction– owing to their substantially lower energy consumption and potential for significant total cost of ownership reduction. Not only do they require as much as 40% less energy than traditional reduction methods, but their wearable …
