Calculating Power Draw when sizing Ball Mills Grinding
I’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 changeA feature of ball mills is their high specific energy consumption A mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity, that is, during the grinding of material Therefore, it is most disadvantageous to use a ball mill at less than full capacityBall Mill an overview | ScienceDirect Topics
