我国过去常用煤的可磨度、灰份、含硫量来判断煤对磨煤机易磨件的磨损强烈程度,根据长期实践结果,上述指标不能完全反映煤的磨损特性,需要根据试验建立煤的磨损指数。经过1974～1979年的几年工作,设计了冲刷磨损试验装置,试验得出了表征煤的磨损性大小的磨损指数;在与实际风扇磨和中速磨相对比的基础上证明了这种表示法的正 According to the results of long-term practice, the above indexes can not fully reflect the wear characteristics of coal, and it is necessary to set up the coal according to the experiment Wear index. After several years of operation from 1974 to 1979, a scouring wear test apparatus was designed and the abrasion index characterizing the abrasiveness of the coal was tested. This indication was demonstrated on the basis of comparison with the actual fan mill and medium speed mill Fa is positive
