had decreased for the -2 mm +1.4 mm mono-size feed compared to the bigger -4 mm +2.8 mm mono-size feed. This therefore shows that should the material feed size continue to decrease, the smaller balls will perform better than the larger balls during milling, as was mentioned by Katubilwa et al. Effect of ball diameter size on mill power draw
One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm. An empirical model from "Emerging Trends in Mineral Processing", 2005, is ...
When the speed of the ball mill is fixed and the ball loading is 30% of the total capacity of the cylinder, the ball's movement is mainly sliding, but it has begun to pour. When the ball load exceeds 40%, the ball is pouring; When it reaches 50%, the surface of the ball is just on the diameter line of the cylinder, so it is easy to pour which ...

The material works its way through the ball mill, which turns about 35 RPM, with the water addition. To the discharge, they will go on to the shaker tables for concentration. Here are three different size balls we use. And you add equal amounts of each size ball when you charge the mill. And then as the balls wear, you keep putting in larger balls.
