Freeing up milling capacity in a SAG mill & ball mill

Jul 08, 2016 The throughput capacity and efficiency of a SAG mill are affected by the significant recirculated load derived from over-size discharge product (critical size “pebble” discharge) that is screened out and may be stockpiled or requires secondary crushing prior to re-introduction to the SAG mill feed. Where the SAG mill/ball mill circuit is
