The effects of ball diameter and revolution speed on the mean particle size (d 50) of the limestone ground at different time intervals are shown in Fig. 1. For all ball sizes employed here, d 50 decreased for the first 30 min of grinding and remained almost invariable for grinding periods longer than 60 min.

Why use Different Size Balls in a Mill
Having selected the best ball size, it will be seen by referring to tables 27 and 28 that the preferable ball size usually gave the best capacity and efficiency. Also, the preferable ball size coincides closely with the best selective grinding, the main exception being the “plus 10-mesh” series in table 28.

Ball Mills and Ball Charging | Bulk Handling Technologies
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.
