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 .
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. However, in practice waste heat is needed for the raw mill, and four stages .

In the cement industry, suspension preheaters are a series of cyclones and duct vessels used to preheat raw meal. Temperatures progressively increase as the kiln feed moves towards the lower stages. Almost every suspension preheater includes a calciner vessel where additional fuel is burned to support the calcination process.
