Learn MoreI’m interested to know when sizing a new ball mill as to why recirculating load has no effect on the power calculation although it will have effect on volumetric capacity naturally 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
