  • OMC PowerBased Comminution Calculations for Design, Modelling

    The majority of modern grinding circuits include a SAG mill, a ball mill and/or a combination thereof. The use of Bond work indices coupled with other breakage tests, and the appliion of empirical efficiency factors, has become a standard for determining ore competency to calculate specific energy in modern grinding.
