摘要： Method for producing a low-carbon clinker with low energy consumption comprising the following stages: pre-calcination of the limestone present in the raw material, along the pre-calciner and in the cyclone tower; start of the clinkering process with the raw material inlet after pre-calcination, at a temperature higher than 1400°C and with a C 3 S content above 60%; cooling the material, and finally introduction of 5 to 30% of silico-aluminous materials relative to the mass of material which is here processed in the cooling stage, at the cooler head.
