Batch breakage kinetic tests were performed in a mill of 0.3 m diameter for a range of mill conditions. Accurate simulation required the measurement and use of factors which accelerated the specific rates of breakage of the top sizes as finer material accumulated in the slurry. These factors depended on the size distribution expressed relative to the top size, not the absolute size, suggesting ...
