Bond Impact Crushing Work Index Procedure and Table of
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 represented by the product – the feed A crude test 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 determinedBond Work Index Tests Grinding Solutions LtdThe Bond work index (Bond, 1960) is based on Bond’s law, which states that the energy consumed is proportional to the 15 power of particle size rather than the square of Rittinger’s law Accordingly, the energy consumed in reducing the particle size from x F to x p (both measured as 80% undersizeBond Work Index an overview ScienceDirect TopicsThe Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test Its value constitutes ore characteristic and is used for industrial comminution plants designing Determining the Bond work index value is quite complicated timeconsuming andgiratory crusher bond work indexThe 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 sizeBond Tests SGS
CORRELATION BETWEEN BOND WORK INDEX AND MECHANICAL
The Bond work index is regarded as one of the crushing resistance; it can therefore be presumed that the Bond work index is correlated to the mechanical properties of materialsIndependent of this it can be used in powerbased calculations, which in conjunction with the Bond ball work index test, enable the prediction of the specific energy of comminution circuits where such circuits include combinations of any of the following equipment:USING THE SMC TEST® TO PREDICT COMMINUTION CIRCUIT Bond Work Index For Coal In Crusher The test determines the bond impact work index which is used with bonds 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 orBond Work Index For Coal In Crusher SPECIAL Mining machineBond Work Index For Coal In Crusher SPECIAL Mining machine Jan 21 2015 coal crushing work index youtube 14 oct 2013 bond work index for coal in crusher crusher machine bauxite crushing bond work index crusher plant bonds crushing law and work index chemical engineering stop bonds law may 14 2010 where kb is a constant that depends on the type of machine and on the material bond work index crusher sokolnicejhczThe Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test Its value constitutes ore characteristic and is used for industrial comminution plants designing Determining the Bond work index value is quite complicated timeconsuming andgiratory crusher bond work index
