Achieving particle size reduction with a multirow cage mill

The mill can achieve a size-reduction ratio (the ratio of feed particle size to final product particle size) as high as 40-to-1 in one processing pass. The cage mill’s high size-reduction ratio results from its crushing mechanism: impact rather than compression. While a compression mill, such as a jaw or roll crusher,

Particle Size Distribution of Grinding Mill Products

Apr 27, 2019  The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions. For light ball loads the ball mill is less efficient as might be expected.
