Sizing acrushercan be done reliably calculated thanks to the Impact/CrushingWork Indexand the testwork research done by Fred Chester Bond and his 1952 paper. According to Bond’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. A crude test ...
