一、分级效率对磨机产量的影响当前国内外选厂的分级设备,尤其是细粒分级设备的分级效率都比较低,通常为20～45%,有的甚至低于10%,这就严重的影响磨机产量,而且对选别指标也极其不利。关于分级效率对磨机产量的影响,可以从磨矿动力学得到推导。根据磨矿理论,磨机的磨矿速度与磨机中未磨碎的粗粒含量成比例,即 First, the grading efficiency of the mill output At present, the selection of domestic and foreign plant grading equipment, especially grading equipment grading efficiency are relatively low, usually 20 to 45%, and some even less than 10%, which is serious The impact of mill output, but also on the sorting index is also extremely unfavorable. The effect of the classification efficiency on the mill output can be deduced from the grinding kinetics. According to the grinding theory, the grinding speed of the mill is proportional to the content of the unmilled coarse grains in the mill, ie
