    Bond Impact Crushing Work Index

    Sizing a crusher can be done reliably calculated thanks to the ImpactCrushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bonds Third Theory of Comminution the workenergy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product – the feed.
