1、存在問題
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">最近兩年，熟料冷卻效果差、熱回收效率低，造成煙室溫度高，二、三次風溫低。二段來料溫度高，二段用的是圓孔篦板阻力較小，料層較厚（700~800mm），風機的電流只能達到額定電流的50%左右（過大會造成窯頭正壓）。圓孔篦板漏料比較多，因此經常下紅料，給二段傳動、各風室支撐梁以及破碎機軸承都帶來較大的負荷，篦冷機出料溫度達到150~200℃，篦冷機維修率高，嚴重影響了正常生產。近兩年篦冷機的故障主要有：二段傳動軸斷停窯1次、破碎機軸承溫度過高停窯1次及高溫造成的其他故障停窯。
2、原因及技改分析

3、改造效果
