RPMs on a ball mill and a star rolling machine
Alan. Post by Piccolo Pete. 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.
