RPMs on a ball mill and a star rolling machine

Okay, I'm "considering" building a combo machine for ball milling and star rolling. The thing I'm confused about is the RPM of the drums. I always thought a ball mill should be fairly slow because rock tumblers that I've seen are fairly slow - maybe 60 revs per minute. I guess I'm wrong. I've seen recommendations of much higher speeds.

Ball Mills - an overview ScienceDirect Topics

Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64.
