Three samples of iron ore (pellet feed), here named samples A, B and C, were tested in a pilot vertical mill. The samples were also characterized in order to generate parameters for Eqs. (4), (5). The simulations predictions (product size distributions) were satisfactory for the three samples studied when a scaling factor k = 1.35 is used.
