    摘要: A method of producing cement clinker and a second calcined material, wherein the cement clinker is produced in a first production line and the second calcined material is produced from a raw material in a second production line by carrying out the following steps:
    e) optionally drying the raw material in a dryer,
    g) calcining the optionally dried raw material in a rotary kiln to obtain the second calcined material,
    wherein the sensible heat of a hot gas in the first production line is used as a heat source in the calcining step g) for calcining the raw material, and
    wherein the rotary kiln exhaust gas coming from the calcining step g) is introduced into the first production line for the secondary combustion of the rotary kiln exhaust gas.

    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.
