| 摘 要： | 在自行设计的粒煤螺旋输送系统上对粒煤的螺旋输送特性进行了研究。结果表明：粒煤的粒径、外水分及螺旋倾角对其输送特性有显著影响。粒煤的平均粒径越大，外水分越小，其输送速率越大；螺旋倾角越大，输送过程中物料的滑移现象越严重，填充系数越大；粒煤的外水分越大，平均粒径越大，输送过程中的填充系数越大。

| Abstract: | The screw conveying characteristics of granular coal from an screw conveyor was investigated.The results show that coal particle size,moisture content and conveying angle have significant effects on the screw conveying characteristics of granular coal.Screw velocity increases with the increasing of particle size of granular coal and decreases with the increasing of moisture content of granular coal.Increasing the conveying angle leads to serious sliding of the granular coal,and the filling coefficient increases.The filling coefficient increases with the increasing of particle size and moisture content of granular coal. |

| Keywords: | granular coal screw conveyor screw velocity filling coefficient |
