Sizing acrushercan be done reliably calculated thanks to the Impact/CrushingWork 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 thework…
More DetailsThe most widely used parameter to measure ore hardness is the Bond work index Wi. Calculations involving Bond’s work index are generally divided into steps with a different Wi determination for each size class. The low energy crushing work index laboratory test is conducted on ore specimens larger than 50 mm, determining the crushing work index (Wi C, CWi or IWi (impact work index)).
More DetailsThe Bond Low-Energy Impact test can be used to determine the Crusher Work index (CWi), also known as the Impact Work Index. The test determines the impact energy at which a specimen fails and allows approximation of net power requirements for sizingcrushers.The open and closed sized settings for given product sizes can also be determined.
