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
