Mill Speed - Critical Speed. Mill Speed . No matter how large or small a mill, ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar rolling mill, its rotational speed is important to proper and efficient mill operation. Too low a speed and little energy is imparted on the product.

r 1 g nc = (1) 2π R−r where, g(m/s2 ) is the acceleration of gravity, R(m) is the radius of the mill, and r(m) is the radius of the grinding elements. nc (1/s) is the critical speed which can not be exceeded, normally tumbling mills run at 65 to 80% of nc .

At what speed will the mill have to be run if the 100 mm balls are replaced by 50 mm balls, all the other conditions remaining the same? Calculations: 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 = 30.7 rpm. But the mill is operated at a speed of 15 rpm.
