The simulated results indicated that efficient grinding occurs at J = 30 %, for which the specific rate S i is maximized. Validation of the results was also done for a higher J value, 40 %. The approach proposed provides more accurate information for the reliable description of the grinding process and enables the scaleup of laboratory results to larger scale mills.
