1 引言 粗粉分离器是喷煤采用球磨机制粉工序中的一个关键设备,它的作用是将来自球磨机的混合粉分离为成品粉供给喷吹和大颗粒粉返回球磨机再磨。粗粉分离器筛分效率的高低将决定返粉中合格粉的多少和循环倍率的大小,进而直接影响球磨机的出力。
1 Introduction The coarse powder separator is a key equipment in coal pulverizing process of pulverized coal injection. Its role is to separate the mixed powder from the ball mill into the finished powder supply and return the large particle powder to the ball mill for reground. The level of the screening efficiency of the meal separator will determine the amount of the qualified powder and the rate of the circulation rate in the meal, which will directly affect the output of the ball mill.
