摘要
煤的可磨性指数是表示煤研磨成粉时的难易程度的指标,它是一个与煤的其它机械性质如硬度、强度、韧度和脆度等相关的无量纲的物理量。可磨性指数数值越大,表示该煤种越易被粉碎,相反则表示该煤种越难被粉碎。据此,通过详细介绍煤的哈氏可磨性指数HGI的测定方法,提出为保证测定结果的准确度所需注意事项。
The grindability index of coal was the index that represented the complexity to pulverize coal, which was a dimemionless physical quantity that associated with the engineering properties as hardness, intensity, viscosity and brittleness. The bigger grindability index numerical value was, the easier it was to smash the coal, or the harder it was to smash the coal. Hereby, through introducing the determination method of Hardgrove gfindability index for coal, this paper proposed the matters need attention to guarantee the accuracy of determination result.
