The ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the targetP90. 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.
[email protected]1 Calculation ofball millcapacity. The production capacity of theball millis determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of theball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
Ball mill shape factors in the period prior to 1927 averaged 1.1/1 for 29 center discharge mills and 1.0/1 for 30 peripheral discharge mills. With the resumption of new plant construction after the 1930’s depression, the Morenci concentrator continued the1/1 ratio with its 3.1x 3.1 m (10 x 10 ft) mills.

Although it was developed nearly 50 years ago, Bond‘s method is still useful for calculating necessarymillsizes and power consumption forballand rodmills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based onmilldimensions and feed characteristics, and the application of the results to designinggrindingcircuits.
