Feeding >15mm to a ball mill this size is not typical - much larger ball mills (>21' or 7.0m diameter) typically get 12-16mm feed (from what I have seen in my experience) With regards to 3.5"- 4" media, typically for Ball mills of this size (16'), max size of ball used should be around the 50-60mm.

mineral processing ore effect of ball size in ball mill

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and ...

Toll Grinding, Processing, and Milling Equipment

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 ...
