Get DetailJul 13, 2011· Using a 1.25ball mill, I milled some troughs for the parts to lie in, then drilled and tapped 3/8-16 threaded holes on either side of the trough. I made a strap 3/4" thick to use as a clamp and counterbored the clamp for nylon pads, hoping that these pads would make up for any inconsistencies in the parts
Get DetailVertical planetary ball milloften has fourballgrinding jars installed on one turntable. When the turntable rotates, the jar axis makes planetary movements, the balls and samples inside the tanks are impacted strongly in highspeedmovement, and samples are eventually ground into powder

Get DetailOkay, I'm "considering" building a combo machine forball millingand star rolling. The thing I'm confused about is theRPMof the drums. I always thought aball millshould 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.
