The FC Bond Mill was designed by F. C. Bond for use in determining the Bond Ball Mill Index, a measure of grindability and power required to mill various ores. FC Bond Mills are 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.

The computation of a Bond ball mill work index was empirically calibrated by Fred Bond using a short ton basis. The modern (metric tonne) basis is the following equation: NI43-101 reports often provide P 100 and the work index. To estimate the other parameters, you can assume: the P 80 is 0.92 (P 100, m) 0.96 (see below for details)
