Cyclone preheaters are 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.

The number of cyclone stages in a preheater system largely determines the system heat efficiency. It also depends on the intended use of the heat of the exit gas leaving the system. In modern practice, most of the kiln gases from a preheater or precalciner system are used for drying in both the raw mill and the coal mill.
