26/11/2020 · grinding balls void space calculation. Jan 01, 2016 The fraction of void space between the balls in the ball charge filled by rock, when the mill is at rest, is given by the ratio of J R /(J B φ) = U. Normally, the bulk rock occupies 20–25% of the mill volume and the balls in a ball mill occupy the remaining charge volume during dry 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 change the power calculation.
