Although it was developed nearly 50 years ago, Bond‘s method is still useful for calculating necessarymillsizes and powerconsumptionforballand 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.
InGrinding, selecting (calculate) the correct or optimumballsize that allows for the best and optimum/ideal or target grind size to be achieved by yourball millis an important thing for a Mineral Processing Engineer AKA Metallurgist to do.
