MINING ENERGY CONSUMPTION 2021 CEEC (Coalition for Eco
Comminution, consuming close to 40% of total energy contains a single piece of equipment—the grinding mill—that is typically the largest single consumer in a mining operation. Noting that the comminution area also includes crushing, pumps and other equipment—the grinding mill(s) are normally the largest single energy consumer.
