Fine feed is known to increase SAG mill throughput but the risk is in unintentionally coarsening the SAG mill discharge and transferring the grinding work to the ball mills. Finer feed frequently leads to the socalled barelyautogenous grinding (BAG) condition with a high ball load, low rock load and often an inability to draw full drive power.
