Ball Mills and Ball Charging
Grinding is the process of achieving particle size reduction through attrition and compressive forces at the granular level. The grinding media in a ball mill is typically steel or ceramic balls of varying sizes, depending on the feed size, work index of the ore and the size reduction and distribution required in the discharge.
Optimization of Ball Mill Grinding of a Limestone‐Type …
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
