For a rod millball mill circuit, do not apply a mill diameter correction for the ball mill. If the rod mill feed is produced by open circuit crushing, use a factor of for the rod mill stage only. If the rod mill feed is 80% passing 12 mm or less ( from a closed circuit crusher) do not apply a rod mill efficiency factor.
