The equation for Rittinger's Law can be written as: 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.
Energy requirements in size reduction of solids
--- the range of crushing is the range of basic law of Kick. The slope of cumulative curve varies from m = 0 to m 0.1. the range of coarse grinding is the range of Bond's theory, (rn = — 0.5) and the range of fine grinding is the range of Rittinger's theory ( m = — 1.0 ). - the range of fine grinding from m = —1 to — 3,
