1. 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).
