Calculate Top Ball Size of Grinding MediaEquation Method
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.
