### A New Approach to the Calculation of Work Index and the

The work index Wi was defined by F. Bond as the specific energy (kWh/ton) required to reduce a particulate material from infinite grain size to 100 microns. The calculation is based on the size-energy relationship e1 2=C.(1/x2n–1/x1n ) which for n = 0.5 x1 = ∞ and x2 =100 by definition gives e∞ 100 = Wi and consequently C=10Wi. In theory for a given material the value found for Wi

Equations for power draft capacity and work input for predicting the performance of industrial grinding mills are derived based on torque measurements using a laboratory instrumented mill. These derivations are based on mechanical principles and on the first-order kinetics of the grinding process. Rittinger s Kick s and Bond s laws express work input as work index (Wi) times a particle
