The effect of processing parameters on energy consumption ...

grinding media (steel balls) on power requirements and energy consumption of a ball mill. With constant mass of the steel balls (20, 30 and 40 kg), the agitator shaft speed was increased from 10 to 100% of the maximum speed, which corresponds to a speed of 50 rpm. The power consumption (W) was recorded upon which milling energy consumption (J/kg) has been calculated. The results were ...

Ball Mill - an overview ScienceDirect Topics

A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at full-scale capacity, i.e. during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages:

Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved. You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill. The ore is “hard” and “bulky”.
