(breakage rate) functions generally are a function of the size distribution existing within the mill, as well as of the operating conditions. The variable that can be more readily controlled in a wet ball mill in operation in industry is solids concentration, with selected studies having been conducted for iron ores.

Learn MoreThis is certainly a more logical and intuitive approach than assuming a constant breakage distribution function, as used in the traditional PBM formulation of ball milling. These approaches, however, had the serious limitation of requiring impact energy data, which was very difficult to estimate experimentally.
