Calculate TopBallSize of Grinding Media - Equation & Method

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 onmilldimensionsand feed characteristics, and the application of the results to designing grinding circuits.

grind size. For any process, includingballmillcircuits, we can say that output equals input multiplied by efficiency*. Output = Input x Efficiency In aballmillcircuit, the "output" can be defined as the production rate of fines of the circuit. As for any output,ballmillcircuit output is a function of both its inputs and efficiencies.
