关于Bond闭路球磨功指数试验的研究何剑伟1,2,祖大磊1,2,谭文才1,21. 洛阳矿山机械工程设计研究院有限责任公司2. 矿山重型装备国家重点实验室摘 要:通过对石灰石进行不同粒度下的Bond球磨功指数试验,分析功指数内部参数变化规律,同时将功指数试验转换为工业试验,发现随着磨矿粒度变细,磨矿产能降低,磨机实际单位功耗增加,而功指数并没有明显变化规律,计算单位功耗与实际单位功耗存在一定差异,这种规律和差异值得人们深思和重视.关键词:球磨机;功指数试验;实际单位功耗;计算单位功耗;......
, and the effect of leaching solution on the strength of ore body was discussed, and the mechanism of influence of leaching time on cohesive force and internal friction angle was revealed. The results show... of the ore block is negatively correlated with the leaching time, and the relationship model of the leaching time with the cohesive force and the internal friction angle is established respectively......
