Predicting SAG/AG Mill and HPGR Specific Energy

2016-7-13  The specific comminution energy (Ecs) has the units kWh/t and is the energy applied during impact breakage. As the impact energy is varied, so does the t10. Higher impact energies produce higher values of t10, which is reflectedin products with finer size distributions. The A and b parameters, in conjunction with equation 1, are used in AG/SAG mill modelling for predicting how rocks break inside the mill.
