Clinker cooling is one of the important processes in cement production. Improving the cooling effect is not only beneficial to improve the quality and grindability of clinker, reduce the power consumption of the cement mill, but also can reduce the clinker temperature, recover the waste heat, and create favorable conditions for subsequent cement handling, storage, or transportation.
