The ball size distribution was calculated to simulate a periodic top-up using 37.5 mm balls. If one assumes a constant wear rate (mm/h), the size distribution of balls has equal numbers in each linear interval of size. Hence, the steady-state mass in these intervals is proportional to the cube of the average diameters of the intervals.
