Modelling and simulation of particle breakage in impact

Dec 10, 2004 Recall the size distribution model for crushers developed by Whiten 1972 and shown in Fig. 1.The particles are characterized by their size distribution that is represented in a discrete form by the vectors f feed and p product, respectively. Each component of f and p represents the mass fraction of the corresponding size class in the feed and the product, respectively.
