按照运行规程要求,我厂双锥形钢球磨煤机每运行2500～3000小时后,因磨内小球增多,影响制粉出力,必须停役选球,以将直径小于φ15毫米的小球清除掉。每选球一次历时5至7天。要将磨内55吨钢球甩出,劳动量相当繁重,且影响机组负荷。我厂根据磨内小球经常被气粉流吹到磨煤机出口料斗处和出口料斗严重磨损的实际情况,又根据磨煤机的转动方向,在磨煤机出口料斗倾斜段中间(磨损
In accordance with the requirements of operating procedures, I plant double cone-shaped ball mill every 2500 to 3000 hours of operation, the ball due to an increase in the mill, affecting the powder output, the ball must be stopped playing ball to diameter less than φ15 mm clear the ball Off Each ball once took 5 to 7 days. Throw 55 tons of steel balls inside the mill, the amount of labor is very heavy, and affect the unit load. According to the actual situation that the mill ball is often blown by the gas powder flow to the outlet hopper of the coal mill and the serious abrasion of the outlet hopper, according to the rotation direction of the coal mill, in the middle of the inclined section of the outlet hopper of the coal mill
