Method and device for the production of a hydraulic binding agent

A method for the production of a hydraulic binding agent from a plurality of raw material components, comprising the steps of:

• grinding first raw material components to a first raw meal with a first mineralogical and/or chemical composition, and subsequently grinding second raw material components to a second raw meal having a second mineralogical and/or chemical composition different from that of the first raw meal,
• analyzing the mineralogical and/or chemical compositions of the first and second raw meals respectively,
• providing first and second separate raw meal silos respectively for the analyzed first and second raw meals,
• filling the first and second silos respectively with the analyzed first and second raw meals of different mineralogical and/or chemical compositions,
• fixing a targeted composition of the first and second raw meals to be burned to form a clinker,
• controlled extracting of the analyzed first and second raw meals from the first and second raw meal silos as a function of the analyzed first and second raw meal compositions,
• transporting the targeted composition of the first and second raw meals to be burned directly to the combustion plant after the controlled extracting step and without further storage in a silo,
• burning the targeted composition of the first and second raw meals to clinker in a combustion plant,
• determining the mineralogical and/or chemical composition of the clinker,
• using a targeted composition of the clinker for further control of the controlled extracting step of the analyzed first and second raw meals from the first and second raw meal silos, and
• finally grinding the clinker together with further inter-grinding materials.
