以盘式搅拌磨为超细粉碎设备，系统地研究了粉碎法制备超细煤系煅烧高岭土粉体的工艺参数。结果表明，矿浆浓度、磨矿时间、研磨介质添加量和配比、叶轮搅拌速度是制备超细煤系煅烧高岭土粉体的重要工艺参数，合理地选择这些工艺参数。才能制备出粒度－２ｕｍ、含量大于９０％的超细煤系煅烧高岭土粉体。 The process parameters for the preparation of ultra-fine coal-based calcined kaolin powder by pulverizing method are systematically studied by using disc-stirring mill as ultra-fine pulverizing equipment. The results show that the slurry concentration, grinding time, the amount of grinding media and the ratio of mixing impeller speed is the preparation of ultrafine coal calcined kaolin powder process parameters, the reasonable selection of these process parameters. In order to prepare a particle size -2um, content of more than 90% of the ultrafine coal calcined kaolin powder.
