RPMs on a ball mill and a star rolling machine
03:47:49 UTC. Permalink. 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.
