The effect of ball size on mill performance - …
The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases. This equation produces a maximum in S, and the particle size of …
Effect of ball size and powder loading on the …
01.12.2013 · In this figure, the positive influence of the smaller ball size on the milling efficiency is drawn by an arbitrary negative slope with ball size rather than the dependency of d −3, because the dependency of d −3 is valid only in a stationary state of ball packing while the actual ball milling is a dynamic event taking place under the presence of the powder slurry existing between the balls. …

THE OPTIMAL BALL DIAMETER IN A MILL
Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell. Grinding tests were carried out with the samples of
