Ball Mill Rpm Formula

Determine ball mill rpm formula.20170317 a ball mill critical speed actually ball, rod, ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its position onto the shell.The imagery below helps explain what goes on inside a mill.

Ball Mill Rpm Newbie Questions Apc Forum

Ball mill rpm posted in newbie questions ok so i know this is a question i should be able to figure out on my own i thought i know of some web sites that had the equation but i must have been wrong any way the jar is 7.75 inchs wide and 10.5 inchs long and im using 50 cal round musket balls for media it will be half full of media so what rpm should i run it at thanks so much.
