types of preheaters in the cement plant types of preheaters

Task The preheater is a component installed upstream of the calciner and the rotary kiln of a clinker/cement plant. By means of the counterflow principle, the injected raw meal is heated in stages by the upward flow of hot gas, whereby the meal is calcined (deacidified) by up to about 95 %.

  • Cyclone Preheater in Cement Plant Suspension Cement

    Cyclone preheatersare 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.
