Theformulato calculate criticalspeedis given below. N c = 42.305 /sqt(D-d) N c = criticalspeedof themill. D =mill diameterspecified in meters. d = diameter of theball. In practiceBall Millsare driven at aspeedof 50-90% of the criticalspeed, the factor being influenced by economic consideration.

TheFormula derivationends up as follow:Critical Speedis: N c =76.6(D 0.5) where: N c is the criticalspeed,in revolutions per minute, D is themilleffective inside diameter, in feet. Example: amill measuring11’0” diameter inside of new shell liners operates at 17.3 rpm.Critical speed…
