• Freeing up milling capacity in a SAG mill & ball mill

    201691&ensp·&enspWhere the SAG mill/ball mill circuit is the bottleneck in the processing plant the pebble circuit can be a significant factor in limiting overall plant capacity. The pebble circuit recirculating load can be very significant (depending on the ore characteristics and SAG mill operating dynamics).
