Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining. The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.

The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3, the air consumption efficiency will be …
