Abstract:
1. A method for manufacturing a sulfoaluminous or belitic sulfoaluminous clinker from a raw mix formed by a mixture comprising minerals containing calcium, aluminum, silica, iron and sulfur, comprising: at least partially dehydrating and decarbonating the mixture through placement in a vertical kiln comprising a substantially vertical chamber wherein the mixture is heated, the chamber of the vertical kiln being supplied with hot gases the temperature of which is between 900 and 1150° C.; extracting the dehydrated and decarbonated mixture from the vertical kiln and conveying the mixture in a continuous kiln comprising a furnace and a transporting means for transporting the mixture across the furnace; heating the mixture from the vertical kiln by passing the mixture through the furnace via the transporting means such that a clinkerization of the mixture is obtained, an average passing time in the furnace being greater than 15 minutes.
