Feed Size VS Ball Size  Grinding & Classification ...
Feed Size VS Ball Size (7 replies) 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.
