The FCBond Millwas designed by F. C. Bond for use in determining theBond Ball MillIndex, a measure ofgrindabilityand power required to mill various ores. FCBond Millsare used in laboratories throughout the world. A copy of Fred C. Bond’s Method of Crushing and Grinding for determination of the Bond Index is included with each mill. This Ball Mill can be used continuously or it can be used for any number of …
TheBond ball mill grindability testis run in a laboratory until a circulating load of 250% is developed. It provides theBond Ball MillWork Index which expresses the resistance of material to ball milling. This happens after 7–10 grinding cycles, which shows that the procedure is a lengthy and complex one and is therefore susceptible to procedural errors.
