| 摘 要： | 在可磨性指数(HGI)测定回路中嵌入能耗测定模块,并对磨后细粒产品进行激光粒度分析.结果表明,研磨能耗与HGI不呈严格的线性相关关系；磨后产品的粒度分布与比表面积增加规律超出了可磨性指数测定依据面积假说所能解释的范畴.这导致煤的可磨性指数测定结果存在一定偏差. |
| 关 键 词： | 煤炭 可磨性指数 激光粒度分析 比表面积 能量损耗 |

| Abstract: | The energy consumption model was put into the measuring circuit of HGI to measure consumption,and the particle size of grinding product was measured by the laser particle size analyzer.the experimental result shows that the grinding energy don't have the liner correlation with the HGI,The characteristic of size distribution and the increase of special surface area are beyond the category which the HGI can explain based on the area hypothesis.It causes the deviation of the result of HGI of coal. |
| Keywords: | coal HGI laser particle size analysis special surface area energy consumption |
