description The invention relates to a method for producing cement clinker, said method comprising the steps of: - preheating raw meal in a preheater (12), - calcining the preheated raw meal in a calciner (14), - burning the preheated, calcined raw meal in a kiln (16) to obtain cement clinker, - cooling the cement clinker in a cooler (18), - withdrawing, as a bypass gas, some of the exhaust gases flowing out of the kiln (16), - cooling the bypass gas in a mixing chamber (60) using a cooling gas, and - separating dust contained in the bypass gas, wherein at least some or all of the cooling gas is formed from the bypass gas and/or the exhaust gas from the calciner, and wherein the cooling gas is introduced into the mixing chamber (60) at a ratio of 2-10 to 1 in relation to the bypass gas. La presente invención se refiere a un procedimiento para la fabricación de clínker que presenta las siguientes etapas: - precalentamiento de la harina cruda en un precalentador (12), - calcinación de la harina cruda precalentada en un calcinador (14), - cocción de la harina cruda precalentada y calcinada en un horno (16) para obtener clínker, - enfriamiento del clínker en un enfriador (18), - desviación de una parte de los gases de escape de horno (16) como gas de derivación, - enfriamiento del gas de derivación en una cámara de mezcla (60) con un gas refrigerante, y - separación del polvo contenido en el gas de derivación, formándose el gas refrigerante total o al menos parcialmente a partir del gas de derivación y/o del gas de escape del calcinador e introduciéndose el gas refrigerante en la cámara de mezcla (60) en una proporción de 2-10 a 1 respecto al gas de derivación.
