陕西省建筑科学研究所和省建筑构件厂合作,建成了我国第一条在混凝土中掺加湿磨粉煤灰的生产线,最近已经通过省级鉴定,认为这项成果为粉煤灰的综合利用开辟了新途径。这条工艺线的特点是:①采用改造后的砂立分散磨代替球磨机,分散效率高,耗电量小,操作方便。②采用电磁控制计量粉煤灰料浆,精度在2%左右,计量准 Shaanxi Provincial Institute of Building Research cooperated with the Provincial Building Component Factory to build the first production line in China with wet milled fly ash. Recently, it has passed the provincial appraisal, and believes that this achievement will be used for the comprehensive utilization of fly ash. A new approach. The characteristics of this process line are: (1) The use of a modified sand mill dispersive grinding mill instead of a ball mill has high dispersion efficiency, low power consumption, and easy operation. 2 Electromagnetically controlled fly ash slurry is used, with an accuracy of about 2%.
