Cement Kilns: Suspension preheater kilns

After separation by the cyclone, the raw meal passes out through a one-way valve which prevents hot gas from coming up the feed pipe. The more stages are used, the more efficient the preheater is. But each stage increases the pressure drop across which the kiln fan must work, and with more than six stages, the fan power requirement is prohibitive.

Fire and Explosion Hazards in Cement Manufacturing Industries

3) On-Site Power Plants. Cement manufacturing is a very energy intensive process. As such, on-site power plants are increasingly being used to meet energy demands of the cement plant. Some of the fire hazards associated with on-site power plants include fire in power house buildings due to ignition of lube oil.


The raw meal processed in the kiln first passes through the preheater absorbing the heat content of the kiln and PYROCLON® gases minimizing the heat consumption of the system. KHD Preheaters with modern designed cyclones produce low pressure drops and are high in separation efficiency.
