串联式双轴向挡板分离器在两种双进双出球磨机上的应用分析

The application analysis of the series biaxial baffle separator on the double -in and double -out tube mill

介绍了串联式双轴向挡板煤粉分离器的发展历程，及其在两种类型双进双出球磨机上的改造应用。改造前后煤粉细度、磨机出力和磨煤单耗等数据的对比分析表明：改造成功有效，不仅有效地降低了煤粉细度，还改善了分离器易堵塞的状况，提高了锅炉运行的经济性和安全性，这也说明该型分离器能够适应和满足双进双出球磨机的需要。

The paper presents the development progress of the biaxial baffle separator and the reform and application on the double - in and double - out tube mill. According to the comparative analysis of coal fineness, mill output and coal mill consumption, it has been proved that the reforming is effective which embodies not only on elevating the coal fineness, but on the improving the condition of the separator blockage result in the developing of the economics and safety of the boiler operation. It has also proved that the separator is a- ble to adopted and satisfied the requirement of the double - in and double - out tube mill
