Get PriceThe point where the mill becomes a centrifuge is called the "critical speed" and ball mills usually operate at65 to 75 of the critical speed ball mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns
Get PriceThe critical speed n rpm when the balls remain attached to the wall with the aid of centrifugal force is n 423 d m where dm is the mill diameter in meters the optimum rotational speed is usually set at6580 of the critical speed
Get PriceMill critical speed determination the "critical speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shells inside surface this is the rotational speed where balls will not fall away from the mills shell result 1 this mill would need to spin at rpm to be at100 critical speed
Get PriceBall mill critical speed transsport the critical speed of ball mill is given by where r radius of ball mill r radius of ball for r 1000 mm and r 50 mm n c 307 rpm but the mill is operated at a speed of 15 rpm therefore the mill is operated at100 x 15307 4886 of critical speed online chat calculating critical speed in a ball mill products
