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.

Cement kiln - Wikipedia

Emissions from cement works are determined both by continuous and discontinuous measuring methods, which are described in corresponding national guidelines and standards. Continuous measurement is primarily used for dust, NOx and SO2, while the remaining parameters relevant pursuant to ambient pollution legislation are usually determined discontinuously by individual measurements. The following descriptions of emissions refer to modern kiln plants based on dry process technology.

Cement Kilns: Suspension preheater kilns

This process is repeated a number of times - typically three to six - by stacking "riser" ducts and cyclones on top of one another in a tower. By repeated heat exchange, most of the heat in the kiln exhaust gas can be captured, while heating the rawmix to calcination temperature. Such heat as escapes the preheater is used to heat the rawmill.
