Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.
Here this Ball Mill Design Calculator. Where the finished product does not have to be uniform, a ball mill may be operated in open circuit, but where the finished product must be uniform it is essential that the grinding mill be used in closed circuit with a screen, if a coarse product is desired, and with a classifier if a fine product is ...
There is a mathematical solution to this problem – the Bond formula. It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below: B – the grinding balls diameter, mm; A – the correction factor (for grinding balls A = 20,17; for cilpence A = 18,15);

to ball filling variation in the mill. The results obtained from this work show, the ball filling percentage variation is between 1.2– 3.7% which is lower than mill ball filling percentage, according to the designed conditions (15%). In addition, acquired load samplings result for mill ball filling was 1.3%.

grinding. Each of these theories was useful in the design and scale up of' ball mill operations, however they told little of the expected size distributions, and most importantly gave no indication of liberation. Later work done by Hukki (1975) attempted to show the validity of each theory within a certain particle size range.
The Ball Mill Finish Calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop. The finish of the part will be determined by the height of the scallop, amd the scallop will be determined by the stepover distance ...

benchmarking SAG and AG mills in a large number of plants. One outstanding achievement of this program (commercial development), was the discovery that in the range of ~0.4 to ~3mm T80, the energy consumed in either a SAG mill or a ball mill to make a size reduction in this range would be equal and could be estimated using Bond equations.
