Dependent upon the Material and the Process! I seen feed as large as 100mm on soft material. There are specialty rod mills where you target a low ratio of reduction such as end and center peripheral discharge than feed need to be targeted to product size required based upon the calculate reduction ratio in the rod mill.
The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power. When calculating rod mill power for a rod millball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed.
Reduction ratios of 15:1 used to be the norm for quality applications ( engineering steels) some 1020 years ago, but even this expectation has fallen with the advent of modern continuous casting practices. Reduction ratios as low as 8:1 are currently acceptable for many high quality long product applications: Residuals
