  • 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 per revolution, G, andThe Bond work index test is a standard method of ore characterization used to assess the energy required for size reduction, and finds wide application in the design of comminution circuits [18,20,19,20] The work index indicates the resistance of the material to grindingCharacterization and Comminution Studies of LowGrade

  • QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE

    Abstract: The 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 theThe 80% passing size P of the broken rock must be measured by size analysis or must be estimated to obtain the blasting work index Two blasting tests (Bond, 1954) on Taconite iron ore in Minnesota five years ago gave work index values of 145 and 135, or an average of 140, which compares with 147 recently obtained in crushing this ore inThe Work Index In Blasting | US Rock Mechanics
