在选矿生产中,磨矿费用和能耗所占的比例最高,一般为50～60％。因此,如何提高磨矿作业效率,以便在给定的技术条件下,用尽可能低的能耗来获得尽可能高的处理量,并避免过磨,对改善选矿厂的技术经济指标,具有很大的实际意义。 影响磨矿作业效率的因素很多,其中,与磨矿机构成闭路循环的分级设备的工作效率是重要的影响因素之一。
In dressing production, the highest proportion of grinding costs and energy consumption, usually 50 to 60%. Therefore, how to improve the efficiency of grinding operations so as to obtain the highest possible throughput with the lowest possible energy consumption under the given technical conditions and to avoid over-grinding, which is of great importance to improving the technical and economic indicators of the beneficiation plant Big practical significance. There are many factors that affect the efficiency of the grinding operation. Among them, the working efficiency of the grading equipment that forms a closed circuit with the grinding machine is one of the important factors.
