The present study represents the algorithm using Fortran language in order to simplify the previous method for the calculation of the Bond\\\'s grinding work index. The primary data used in this algorithm, such as particle size of ground product and circulation load, make possible the simultaneous calculation of the stable revolution number of mill, the grindability, and the grinding work index. The procedure for the data inputs and calculations is minimized by 93 percent and is stable, hence to yield better grinding work index than that of the previous method with problems of increasing cycle number originated from its complex calculation nature.
