摘　　要：分析了中梁山煤的基本性质,对中梁山微粉煤进行摩擦电选实验研究,通过对电压、风量、粒度、湿度、不同分选室结构等因素的影响试验发现风量、电压越大分选效果越好,粒度在<400目时分选效果最好,湿度越小,分选效果越好。This paper introduces the property of Zhongliangshan coal , thetriboelectrostatic benefication experiment of this coal has been done , this study has improved that voltage, velocity of the wind, size, moisture, the different separator and so on do some effect in this experiment, the higher of the voltage and velocity of the wind, the better of the effect, when the size 〈 400 mesh, and the moisture is lower , the effect of triboelectrostatic benefication of the fine coal is better.
