论文部分内容阅读
本文第二部分涉及影响磨矿过程和设备寿命的一些因素,如磨矿负荷占磨矿机容积系数,磨矿机装球量或装棒量,磨矿机和磨矿介质的磨损以及以临界转速表示的磨矿机转速。文章还讨论了磨矿机直径,球负荷向下滑动,给料过大粒比例,分级机性能和功率消耗。还提出换算闭路功值至开路功值时的开路相乘系数。文章最后提出当实验室可磨度和反击破碎试验得到不同的功指数值时功指数变化的校正系数。
The second part of this article deals with factors that affect the grinding process and the life of the equipment, such as the volumetric load of the grinding mill, the volumetric capacity of the mills, the amount of loading or loading of the mills, the wear of the mills and grinding media, Speed that mill speed. The article also discusses the diameter of the mill, sliding down the ball load, oversized feed ratio, classifier performance, and power consumption. Also proposed conversion of closed-circuit value to the value of open-circuit power multiplication factor. Finally, the paper proposes the correction coefficient of the change of work index when the laboratory workability and counterattack test results in different work values.
