  • Energy absorption and specific breakage rate of particles

    Abstract A detailed analysis of the specific breakage rate and mill power data on dry ball milling of three individual minerals and their binary mixtures has been carried out. The energy split model of Kapur and Fuerstenau has been examined and shown to be incorrect. A new model has been proposed. The basic postulates are (i) only a small fraction λ of the net energy input to the mill is
