1、存在问题
normal style="LAYOUT-GRID-MODE: char; MARGIN: 0cm 0cm 0pt; LINE-HEIGHT: 200%; TEXT-INDENT: 21pt; mso-char-indent-count: 2.0; mso-layout-grid-align: none">最近两年，熟料冷却效果差、热回收效率低，造成烟室温度高，二、三次风温低。二段来料温度高，二段用的是圆孔篦板阻力较小，料层较厚（700~800mm），风机的电流只能达到额定电流的50%左右（过大会造成窑头正压）。圆孔篦板漏料比较多，因此经常下红料，给二段传动、各风室支撑梁以及破碎机轴承都带来较大的负荷，篦冷机出料温度达到150~200℃，篦冷机维修率高，严重影响了正常生产。近两年篦冷机的故障主要有：二段传动轴断停窑1次、破碎机轴承温度过高停窑1次及高温造成的其他故障停窑。
2、原因及技改分析

3、改造效果
