The effect of ball size on the energy efficiency of hybrid

There is an optimum range of energy partitioning between the high-pressure roll mill and the ball mill in the hybrid system. The increased efficiency of hybrid grinding is related to the particle damage imparted by the roll mill, as evidenced by the increased breakage rates of high-pressure roll mill product relative to particles that had not
