The grindability of a material is the only factor used to determine the required size of a grinding machine. Although, Bond's grindabilty test is widely used to the estimate power required of an industrial grinding mill. Recently, kinetic model has been mostly used to the design of grinding circuits.In this study, the relationship between the Bond's grindability (G(bg)) and breakage parameters (S-i, alpha(T), gamma and beta) were examined. The validity of the obtained relationship parameters of S-i, alpha(T), gamma and beta has been confirmed with correlation coefficients of 0.96, 0.92, 0.90 and 0.78, respectively, through a regression analysis of samples of limestone.
