For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going through effectively, but if we reduce the recirculating load to 200% at 900 tph it will not change the power calculation. However if we increase the fresh feed by 100 TPH the power calculation goes up as does the size of mill required.
