    For this work, our objective is to identify a feed size distribution from which maximum production of the target size can be achieved. Just to shed light on the target size, the mill product is defined by three classes; m 1 the feed size, m 2 the target size (−150 + 25 µm) and m 3 being the fines (<25 µm).

  • 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.
