Rpms On A Ball Mill And A Star Rolling Machine
Thought a ball mill should be fairly slow because rock tumblers that ive seen are fairly slow maybe 60 revs per minute i guess im wrong ive seen recommendations of much higher speeds of course that is the speed of the motor when the belt wheel and drum ratio come into play i guess the rotation of the drum is much slower than
