  • Correction of Bond Ball Mill Work Index Test for Closing

    The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis to another. The proposed model consists of two components, the variable coefficient that is determined from a specific work index determination and a fixed exponent determined by a calibration procedure. The model has the benefit of retaining the variability in hardness that is built
