Cyclone preheater in cement plant

Production Capacity: 200-2500t/d

Application: customization service 

The cyclone preheater, also called suspension preheater, is a kind of preheater in cement plant. As the core equipment of dry method cement production line, cyclone preheater use suspension preheating to preheat and partly decompose the cementraw mix, shorten the length of rotary kiln, fully mix raw mix and hot air in the kiln, increase heat exchange rate, which promote the efficiency of rotary kiln plant and reduce the energy consumption.

The cyclone preheater can take full advantage of heat in the cement rotary kiln, reduce the heat consumption of clinker production, and reduce the room occupied. To meet ideal effect, AGICO Cement design preheater in the cement plant according to different regions and scale of production.

Advantages of suspension preheater

  • High productivity: the cyclone preheater adopts multistage cycle suspension preheating to improve the production rate.
  • Low investment: due to the reasonable structure of cyclone preheater, reduce the problems of equipment, cost-effective, low investment and higher benefits.
  • Low energy consumption: make full use of heat in the kiln, reduce the energy consumption of clinker production, and reduce the room required.
  • Wide application: custom-design cyclone preheater can be provided according to different regions and production scale, turnkey project of preheater.

Working principle of cyclone preheater

The cyclone preheater is consist of six parts, including the upper feeding system, preheater, roller pusher, hydraulic system, lower feeding room, and etc.

preheater in cement plant

The cyclone preheater use the high-temperature airflow accumulated in the kiln and adopts multi-stage circulating suspension preheating method to make the raw material powder and the hot air flow fully exchange, complete the suspension preheating and partial raw material decomposition, and prepare for the clinker production.
