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
