| 摘 要： | 本文从连续损伤理论的观点出发,将矿岩粉碎过程描述为在外部荷载作用下矿岩颗粒内部微缺陷(损伤)演化和繁衍的过程。导出了粉碎能耗与产品粒度分布的理论表达式。该式包含了所有传统的理论,同时较传统的能量分配观点前进了一步。

| Abstract: | 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. |
