2500t/d水泥熟料生产线冷却机升级新途径

A New Way to Upgrade Cooler of 2500t/d Cement Clinker Line

某水泥熟料2500t/d生产线原冷却机存在出冷却机熟料温度较高,二、三次风温较低,热回收效率低等问题,经采取保留冷却机壳体,并将冷却机内部更换为步进式冷却机篦床、传动等部件,尾部增加尾置辊式破碎机等措施后,热回收效果明显提升,出冷却机熟料温度90℃~95℃,热回收效率为74.9%,冷却机工艺指标在国内同规格生产线中达到先进水平。

The cooler of the 2500t/d cement clinker line,shows problems after several years running.The temperature of clinker out of cooler is higher,the temperature of secondary and tertiary air is lower,and the efficiency of heat recovery is lower.Then it keeps the upper and lower cases,reforms the inner of cooler with SINO-WALK grate,drive devices and end roller crusher.The output and heat recovery efficiency are significantly improved.The temperature of clinker out of cooler is 90~95℃,and the heat recovery efficiency is 74.9%.The process parameters reach the advanced level in the same scale production lines in China.
