This scenario assumes that the mills adoption rate of this technology starts to linearly increase from 0% in 2020 and reach 100% by 2030. The scenarios IRPAG and GOPAG assume 13% energy savings and 25% reduction in ball consumption (Nkwanyana and Loveday, 2017), achieved by the addition of pebbles to ball mills in iron and gold mining, respectively.

A ball mill is a drumgrinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
