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: • universality and high capacity • permanence of a ...

The operating principle of the ball mill

08/02/2017  Energy consumption for ball mills is a function of many factors: the physical properties of the ground material – its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency – no more than 15%. Energy is mainly consumed on the wear of grinding balls and mill housing, friction; heating the material etc.

Energy and Cost Comparisons of HPGR-based Circuits

The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case. The energy reduction for the new flowsheets significantly improved the economics of ...
