Smith and Lee (1968) compared the data obtained by the standard Bond test and the data from the open grinding cycle, i.e. the first grinding cycle of the standard Bond test. Kapur (1970) came to the conclusion that the estimation of the Bond index can be performed on the basis of data from the first two grinding cycles of the standard Bond test.

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 …
