How Coarse can Ball Mill Feed be
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.
