Analyze grinding efficiency by using particle Energy

Oct 18 2016  Although 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 5 7 m ball mill can reach 3.5 MW and only 1 to 5 of this power is directed to size reduction So why are tumbling mills so very inefficient
