Testwork: Bond crushing work index
The 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 apparatus.

Bond Work Index
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 ...
