SAG Ball consumption is "average" at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t. Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved. You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill. The ore is "hard" and "bulky".
The formula used to calculate the grind media distribution in a ball mill is as follows: Grind media (g) = Crushing force (tons) x Circumference of media (cm) x Diameter of …
A ball mill is a tumbling mill that utilizes steel balls as grinding media to grind materials.

The calculations are based upon measurements giving the amount of the size reduction by the difference in the size distributions of the feed (F) and the product (P).
The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely …
A wide range of materials is used to resist wear in comminution processes (Durman, 1988, Moema et al., 2009).The abrasiveness of the material being processed is of prime importance in determining the absolute wear rate of the grinding media, but conflicting characteristics of high hardness for maximum wear resistance and adequate …

APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principles is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the mill—is a function of the percentage of the volume of the mill it occupies.
1. Introduction. Grinding operation is used extensively in the industry of beneficiation, metallurgy, chemical engineering, and electric power. Assisted by the impact and abrasion between media (steel ball, steel rod, gravel, ceramic ball) and ore, the grinding operation reduces the particle size in the mill [[1], [2], [3]].To produce the …
