The balls to powder ratio (BPR) and powder type were investigated in relation to the particle size. The study showed that the combination of the BPR and powder type affects the particle size result. The optimum of BPR at 12 with the number of balls is 60 pieces, and the filling rate is 10.13%. The result shows that the horizontal ball mill able ...

the performance of dry ball mill grinding was investigated for a limestone-type brecciated uranium ore. The optimum grinding was obtained with the combination of dierent balls (12.7–37.5 mm) and interstitial lling of 50% (20% ball lling ratio at xed material lling ratio= 4%). The net power consumption in a ball mill is proportional to the
