| description | The invention concerns a method for making a cement (1) from a mixture (2) comprising CaCO3, Al2O3 and/or Al(OH)3, CaSO4, SiO2 and/or a product containing silica or silicates such as clay, said compounds being present in anhydrous or hydrated form, separately or in combination. Said method is characterised in that the mixture (2) is treated until a clinker is obtained by displacement in a kiln (4) firebox (3), in a layer (5) of substantially constant thickness, at substantially constant speed, along a treatment path (6) subjected to a positive temperature gradient, and for a treatment period during which the mixture (2) remains below its melting point, and the clinkered mixture (7) is cooled at the output of the treatment path (6).
L'invention concerne un procédé de fabrication d'un ciment (1) à partir d'un mélange (2) comprenant CaCO3, Al2O3 et/ou Al(OH)3, CaSO4, SiO2 et/ou un produit contenant de la silice ou des silicates tel que l'argile, ces composés étant présents sous forme anhydre ou hydratée, individuellement ou en combinaison. Ce procédé est caractérisé en ce que le mélange (2) est traité jusqu'à clinkérisation par déplacement dans un foyer (3) de four (4), en nappe (5) d'épaisseur sensiblement constante, à vitesse sensiblement constante, le long d'un trajet de traitement (6) soumis à un gradient positif de température, et pendant un temps de traitement au cours duquel ce mélange (2) reste en dessous de sa température de fusion, et en ce que le mélange clinkérisé (7) est refroidi en sortie de trajet de traitement (6). |
