## Bond Work Index an overview | ScienceDirect Topics

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 perThe Bond low energy impact (crushing) work index test is specified to be performed on rock specimens between 50 mm and 75 mm in effective diameter NQdiameter drill core, frequently used in mineral exploration programs does not meet that specification, itEffect of core diameter on the Bond impact crushing work

## Operating work index is not the specific energy

Oct 24, 2018· The work index can either be measured in the laboratory (the Bond ball mill work index determination is a common example) or it can be calculated from the operating performance of a millingThe Bond lowenergy impact crushing work index (more informally, the Bond crushing work index) is not as common as the Bond ball mill work index, and it is a notoriously noisy test The test is a 'perspecimen' test where individual specimens of prepared rock are handpicked by the test operator and placed into the apparatusTestwork: Bond crushing work index
