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. Of
