Abstract: Described is a plant for manufacturing cement clinker comprising a preheater (1) which comprises at least one last cyclone (1d) and at least one next-to-last cyclone (1c) which is connected in series via a gas duct (2c) to and fed with gas from the last cyclone (1d), a calciner (3) which comprises at least one inlet opening (9) for introducing preheated raw meal from the last cyclone (1d), and which is connected to a subsequent separating cyclone (4), a gas duct (2d) which connects the separating cyclone (4) to the last cyclone (1d), and which comprises at least one inlet opening (11) for introducing preheated raw meal from the next-to-last cyclone (1c). The plant is peculiar in that the inlet opening (11) for introducing preheated raw meal from the next-to-last cyclone (1c) into the gas duct (2d) which connects the separating cyclone (4) to the last cyclone (1d) in a vertical plane is located under at least one inlet opening (9) for introducing preheated raw meal from the last cyclone (1d) into the calciner.
