Bond Impact Crushing Work Index Procedure and Table 2015 6 16 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 the feed.pendulum crushing indexpendulum impact crusher La Vitrine une collection Bond Impact Crushing Work Index Both hammers of the pendulum will impact the smallest measured side on the rock The hammers are set to fall again from a higher drop position to input enough energy to break the rock This is done 10 times to obtain 10 breaks and the WI kWh/t = 53 49 x Impact Crushing Strength / Specific Gravity of the
