    Apr 25, 2013 II. ENERGY USE IN COMMINUTION Grinding activities in general (including coarse, inter-mediate, and fine grinding) account for 0.5 pct of U.S. primary energy use, 3.8 pct of total U.S. electricity consumption, and 40 pct of total U.S. mining industry energy use. Large energy saving opportunities have been identified in grinding in particular.[1]
