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

The Bond LowEnergy 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 sizing crushers The open and closed sized settings for given product sizes can also be determined

The 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 [38] measured the Bond work index of three ore types using different test screen sizes He produced a correlation between the mass of test screen undersize per revolution, G, and

The 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 openside settings (jaw crushers and gyratory crushers) or closedside settings (cone crushers) for a given product size P80 = 25400 x Oss x (004Wi + 040) P80 = 25400 x Css x 7Ecc x

Note that the Bond ball work index test should be carried out with a closing screen size which gives a final product P80 similar to that intended for the full scale circuit Conventional Crushers Equation 1 for conventional crushers is written as: f x f x 2 1 c c 2 ic 4 2 W S K M x x 1 (7) wwwsmctesting 4 Where S c = coarse ore hardness parameter which is used in primary and
