A review of the applications of the JK size

The population balance model is based on a rate-size balance around a mill with two sets of breakage functions: a specific rate of breakage function and a breakage distribution function. Since the model parameters are simultaneously fitted to the mill feed and product data, the fitted (or back-calculated) parameters are interrelated, and it is
