    Sizing a crusher can be done reliably calculated thanks to theImpact/Crushing Work Indexand the testwork research done by Fred ChesterBondand his 1952 paper. According toBond’s Third Theory of Comminution, thework/energy input is proportional to the new crack tip length created during particle breakage and equivalent to theworkrepresented by the product – the feed.
