Feed Size VS Ball Size Grinding & Classification

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 often used:

2018-6-1  Mass fraction M3 vs. milling time for various grinding times at a media fill level of J = 20% (a) feed size = -1700 + 850 μm (b) feed size = -1 180 + 850 μm. Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used.

Ball Mill an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
