%X Based upon the aspect of continuous damaging, the process of ore com-minution may be described as the growth and propagation of the microcraks in theore grains under external loading, and a theoretical expression has been developed onthe relationship between the grain size distribution and the total energy consumptionduring entire ore comminution process. The energy consumed totally may be consi-dered to consist of two portions: i.e., with fresh crack surfaces growth and withcrack propagation. The expression proposed seems to be an advance over previousconventional ones, especially that from the viewpoint of energy distribution.
