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]].

The size of grinding media is the primary factor that affects the overall milling efficiency of a ball mill ( power consumption and particle size breakage). This article tackles the lack of a design tool that could help choose the ball loading composition in mills. Such a tool enables the maximization of the exposed surface area per unit energy (cm2/J).

To have a pulp as dilute as 20 percent solids, the ball load was drawn down to 30 percent volume and the ore charge proportionately reduced. Water was then added to fill the mill. The results of grinding were much like those with 33 percent solids. All in all, 33 percent solids was the best for efficiency and selective grinding.
