2008-8-1 · Other similar models for energy consumption, referred to as Kick’s and Rittinger’s equations are shown in Eqs.,. (1) W Bond = C Bond × 1 p 80-1 f 80 (2) W Kick =-C Kick ln p 80 f 80 (3) W Rittinger = C Ritt × 1 p 80-1 f 80. Here, W is the energy consumption per tonne of material crushed, C Bond is the so-called work index of the rock, obtained in a test.
