Optimization of Ball Mill Grinding of a Limestone-Type
The effect of ball size and interstitial filling on 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 different balls (12.7–37.5 mm) and interstitial filling of 50% (20% ball filling ratio at fixed material filling ratio = 4%). The net power …
