Although it was developed nearly 50 years ago, Bond's method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.

The results are shown in table 26. When the conventional mill was loaded to 45 percent ball volume the weight of the balls was 1,271 pounds. When the loading of the mill containing the drum is expressed as 30 percent ball volume, for example, it was a proportional part of the abovementioned loading, namely 847 pounds.
