Product Introduction

Cooler is one of the important machines of the rotary kiln system and its functions are to cool the clinker from the rotary kiln from 1000-1300℃ to below 200℃ and to improve the quality and drinkability of the clinker.

Cooler Features:

  1. The cooler feeding mouth adopts a KID system and pulsating air supply to quickly cool the high-temperature clinker from the kiln.

  2. Increasing the strength and wear resistance of clinker and improving the operation rate of the equipment.

  3. Through cylinder rotary drive adequately heat exchange, which cools the material to below 200℃, at the same time improve the quality of clinker and grinding

  4. The air after cooling the material is all put into the kiln, which is used as the secondary circulating air, thereby reducing the labor intensity and increasing the output.
