    A NOVEL AG-CRUSHER-HPGR CIRCUIT FOR HARD

    AG-CRUSHER-HPGR CIRCUIT A novel HPGR flowsheet was proposed to take advantage of the potential operating cost savings in processing hard rocks, to stabilize production, and to mitigate issues caused by the soft and clayish materials. The proposed flowsheet is shown in Figure 1; evaluation of its capabilities was the object of the research

    Circuits using Cone Crushers and High Pressure Grinding Rolls (HPGR) have proven to be more energy efficient. These comminution devices have during the last two decades been implemented for hard rock materials. These machines are hence suitable subjects for further performance improvement and optimization.

    Jan 01, 2016 Both AG/SAG mills and HPGRs are used over a range of comminution sizes. AG/SAG mills are used in primary milling applications but achieve both coarse particle breakage and fines production—relative to conventional crushing circuits, the product of AG/SAG circuits typically generate more fines. HPGRs are most typically used as a stage of comminution, but
