Use of drilling performance to improve rock-breakage efficiencies:
2020年3月1日Crushing and grinding are some of the most energy-intensive industrial processes in the world. In mines, rock-breakage (comminution) processes comprise a major portion–about 30%-60%–of the total energy consumption [1], [2], [3], [4], [5]. These processes impact not only energy consumption but also mine productivity.
