The mathematical model previously developed for a ring ball mill based on specific rates of breakage, breakage distributions, and primary and secondary classification actions was further refined. In particular, empirical expressions are presented for both primary and secondary classification actions as a function of the mill and classifier geometry as well as the operating conditions. In addition, the scale-up factor with the make-up feed rate determined in a pilot-scale mill was further developed for larger mills. Model simulations based on parameters measured in the Hardgrove mill with the present classification models and scale-up factors correctly predicted the circuit behavior of industrial-scale mill systems. Furthermore, some of the factors affecting the mill performance were investigated with the present simulation model. As a result, the feed size distribution and the total crushing load on balls were found to be the dominant factors.† This report was originally printed in J. Soc.
