The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result 1 This mill would need to spin at RPM to be at 100 critical speed.Aug 15, 2012 The formula was published in Lloyd Sponnenburgh's booklet on ball milling, though he's said it originally comes from commercial information and literature on industrial ball mills. Critical speed is the rpm at which the media will be stuck to the side of the jar based on centripetal force. All of the values in the formula are to be used in inches.
