The optimal ball diameter in a mill 333 The grinding efficiency of the narrow particle size fractions with ball charge of various diameters has been observed through the constant of milling rate k in the equation of the grinding kinetics law for the first order grinding R=R 0
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
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.
