    This equation reverts to the Bond equation (Equation ) by taking the value of B as 12 and integrating; thus, (3.7) E = k 1 P 6 12 − 1 F 6 12 which in effect is the Bond equation. Bond's original work on establishing the energy for size reduction was established in a 2.44 m (8 foot) internal diameter wet grinding overflow type ball mill.

  • 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, and

  • Comminution - Wikipedia

    Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with
