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

MoreBond Work Index For Crushing Coal Delumper75 Lp Crusher. A Bond Ball Mill Work Index test is a standard test for determining the ball mill index of a sample of ore It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO 2006) This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling for estimating the energy required

MoreThe Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic measured the Bond work index of three ore types using different test screen sizes.

MoreThe test determines the Bond Impact Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.
