Energy considerations in compressive and impact crushing

Aug 01, 2008 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.

Comparison between bond crushing energy and fracture

energy is equal to the total accumulated work done by all walls (here the jaws of the crusher) on the granular model of rock specimens that is calculated by the PFC3D software23. It is assumed the fracture energy of rocks is equal to the wall energy per mass of rocks. In this case dynamic and multiple impacts behaviour of the crusher has been neglected.
