In ball mills, balls take up most of charge volume and are the major ore grinding components. The balls do most of the ore size reductions, unlike SAG mills where large ore fragments do most of the size reduction. The missions of the two types of balls are different and the properties required to perform those missions are different. …

The primary difference between a ball mill and a SAG (Semi-Autogenous Grinding) mill lies in their operation mechanisms and the materials they use for grinding. Ball mills utilize steel rods, balls, or similar media to grind materials, whereas SAG mills use a combination of large rocks of the ore and steel balls to perform grinding.
