If you have a pebble crusher, maintain the minimum gap setting possible and allow the system to by-pass some un-crushed pebbles back to the SAG. As long as you maximize the power draw on the crushing unit, you will not lose throughput as a result of crushing fewer tons. (this should also reduce the circulating pebble load in the SAG circuit).Web
