Bond Impact Crushing Work Index -Procedure
Sizing a crusher can be done reliably calculated thanks to the Impact/Crushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond's Third Theory of Comminution, the work/energy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product …

Work Index and Sample Size
The answer to this question is that generally no, the size that the index is measured at does not effect the Bond work index value. Bond work index (BW i) is a measure of the hardness of an ore. This is a quality of the rock, which generally does not change over the size ranges encountered in ball milling.
