The crushers work harder on coarser feeds and will draw more power. Coarsening the feed to the secondary crushers causes a decrease in the amount of fines discharged, so that the circulating load increases. The discharge rate of secondary crusher fines, at some point, becomes more or less constant and the circulating load levels off.
