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. Of course, that is the speed of the motor when the belt ...

What are the differences between ball mill and rod mill ...

 · The working principle of ball mill and rod mill machine is similar, too. That is, the cylinder drives the movement of the grinding medium (lifting the grinding medium to a certain height then dropping). Under the action of centrifugal force and friction, the material is impacted and ground to required size, so as to realize the operation of mineral grinding. BALL MILL VS ROD MILL: what are .

TECHNICAL NOTES 8 GRINDING R. P. King

Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types rod, ball, pebble autogenous and semiautogenous. The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by ...
