Abstract

L'invention concerne un procédé de fabrication de clinker, selon lequel de la farine crue est préchauffée à l'aide des gaz de fumée chauds d'un four à clinker dans un dispositif de préchauffage (3), et la farine crue préchauffée et éventuellement calcinée dans un calcinateur (4) est brûlée dans le four à clinker (2) pour donner du clinker, le dispositif de préchauffage (3) comprenant au moins une ligne constituée d'une pluralité d'échangeurs de chaleur cycloniques (8, 9, 10) pour l'échange de chaleur entre du gaz et des particules en suspension, traversés les uns après les autres par les gaz de fumée du four, dans lesquels la farine crue est graduellement préchauffée. Selon ledit procédé, une partie du flux des gaz de fumée du four est déviée, de sorte que seul un flux résiduel restant des gaz de fumée est utilisé pour préchauffer la farine crue.
