Abstract: In a method for reprocessing wet waste materials containing organic components, in particular sludges in a cement clinker production plant, in which raw meal is preheated in a preheater (3) in countercurrent flow to the hot exhaust gases of a clinker furnace (2), and calcined in a calciner (4) fired with alternative fuels, the wet waste materials are dried in a drying unit (18) using a hot gas produced from the preheater waste heat and the dried waste materials and the drier exhaust gases are discharged from the drying unit (18), wherein the drier exhaust gases are introduced into the calciner (4).

Abstract: In a process for the production of cement clinker, in which raw meal is preheated in a preheater (3) using the hot exhaust gases from a clinker kiln, and the preheated raw meal, which is optionally calcined in a calciner (4), is burned to clinker in the clinker kiln (2), wherein the preheater (3) includes at least one string of a plurality of cyclone suspension-type heat exchangers (8, 9, 10), through which the kiln exhaust gas successively flows and in which the raw meal is preheated in stages, a partial stream of the kiln exhaust gas is diverted such that only a remaining residual stream of the kiln exhaust gas is utilized for preheating the raw meal.
