摘　　要：通过某电厂RP783中速磨和DTM35 0 / 70 0钢球磨变煤种最大出力试验的研究 ,得到一些煤种的可磨性指数不能很好地表证其实际出力。通过分析得出了这些煤种出力低的原因 ,指出了实验室测定的原煤可磨性指数在实际应用中的局限性 ,并讨论了修正可磨性指数需要考虑的煤质因素 。The maximum grinding capacity test results of a model RP783 race pulverizer installed at Zhujiang Power Plant was investigated along with those of a model DTM350/700 ball mill installed at Zhanjiang Power Plant. It has been found that the grindability index of some kinds of coal does not fully reflect their actual grinding capacity. After the cause of the low grinding capacity for these coals has been identified by an analysis the authors point out the practical service limitations of the raw coal grindability index measured in a laboratory. In addition, investigated are the coal quality factors to be considered during the revision of these grindability indexes. The relevant findings can serve as reference data during a more in-depth study by design and operation management personnel of coal pulverizers.
