摘要分析了CLM1700煤磨细度合格率低、电耗高等问题产生的原因，针对煤磨收尘器压差高、系统阻力大等问题进行了改造。通过增加收尘器脉冲阀，增大选粉机出风口管道面积和旋风筒进风口面积等技术措施，收尘器压差由4 500Pa降至1 300Pa，煤粉细度合格率大幅提高，工序电耗由33kW·h/t降至24kW·h/t以下，收到了较好的改造效果。

Abstract: The reasons for the low fineness passing rate and high power consumption of CLM1700 coal mill are analyzed, and the problems such as high differential pressure of coal mill dust collector and high system resistance are rebuilt. Through technical measures such as increasing the dust collector pulse valve, increasing the area of the air outlet pipe of the separator and the area of the air inlet of the cyclone, the differential pressure of the dust collector is reduced from 4 500Pa to 1 300Pa, the passing rate of coal powder fineness is greatly improved, and the process electricity consumption is reduced from 33kW·h/t to less than 24kW·h/t, which receive a good improvement effect.

Key words: coal mill fineness of coal powder process power consumption
