METHOD FOR PRODUCING A LOW-CARBON CLINKER |
| 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 C3S 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. |
