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.

E = K R f c (1/L 2 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick's Law states that the energy is proportional to the size reduction ratio. The equation for Kick's Law can be written as: E = K K f c log e (L 1 /L 2)
