QUANTIFYING THE ADDITIONAL ENERGY CONSUMED …

Steel balls and rods are regularly used as grinding media in tumbling mills to assist with ore breakage. The consumption of this media through wear processes can be viewed as a form of embodied energy consumption, as the mining, smelting, casting, and shipping of media consumes a substantial quantity of "embodied" energy.
