The cement kiln - Understanding Cement

In the diagram above of a precalciner kiln, meal passes down the preheater tower while hot gases rise up, heating the meal. At 'A,' the meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

Preheater Tower and Cement Mill, AGET Heracles Volos Plant

Preheat Towers - HarbisonWalker International

Kiln preheater towers provide heat transfer from hot gases to kiln feed material. The counterflow of gases and material takes place in cyclones, referred to as stages, in the preheat tower. As material flows from the top to bottom of the tower, it is exposed to increasingly higher temperatures as it is prepared to enter the kiln.
