Abstract The cooler of the 2 500t/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.
