通常认为,磨矿效率随磨矿介质球体积硬度比例增长而提高,因而降低了磨损率。每一个球介质的生产者却认为未必是这种情况。球的磨损率因平均体积硬度获得最大值一般减至最小值。但在磨矿介质工艺领域居 It is generally accepted that the grinding efficiency increases with increasing proportion of the volumetric hardness of the grinding media, thereby reducing the wear rate. Producers of every ball medium do not think this is necessarily the case. Ball wear rate due to the average volume hardness obtained maximum is generally reduced to a minimum. However, in the field of grinding media technology
