  • Energy and Cost Comparisons of HPGR-based Circuits E & MJ

    For comparison, the costs for SABC circuits grinding to 160 μm and 75 μm were determined to allow for direct comparison to HPGR-ball mill and HPGR-stirred mill circuits, respectively. The indirect cost was estimated at 45% of direct capital costs and was considered to be within industry standards for the options considered.
