    2017年4月22日· The use of ball mills for reducing crusher product to 85 per cent,: below 200mesh in two stages, as practised at the United Eastern, Tom Reed, and Montana mines, in Arizona, is a distinct advance in fine crushing The simplicity, small floor space and large capacity of these installations are especially notableI’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 changeCalculating Power Draw when sizing Ball Mills Grinding
