Recirculating Load Mill (Grinding) Industries

For instance a mill of 300tph with a 300% recirculating load would have 1200tph going through effectively, but if we reduce the recirculating load to 200% at 900tph 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.
