Efficiency Circle Probability Ball Mill

Oct 18 2016nbsp018332Although mills have great energy consumption only a small part of this energy is converted into actual particle fragmentation As an example Cleary 2000 points out that the power consumption for a 52157 m ball mill can reach 35 MW and only 1 to 5 of this power is directed to size reduction So why are tumbling mills so very inefficient
