Introduction Mineral crushing is the main source of energy consumption in mineral processing. According to statistics, this consumption accounts for about 3550% of the total cost of the mine (Curry et al., 2014), or even higher. It may also account for % of the global electrical energy consumption (NapierMunn, 2015).

MPS mill (rollerrace) model. The most significant difference between the MPS and Emill designs is the grinding mechanism. The MPS mill uses a three rollerrace system instead of the 10 ballrace system deployed in the Emill. The elutriator zone in the MPS mill also appears to be closer to the air classifier entry area.
