Each mill measures about 12m in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.

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.
