Method and device for the production of a hydraulic binding agent

摘要

The invention relates to a method and to apparatus for the production of a hydraulic binding agent from a plurality of raw material components ( 12 a to 12 e), wherein the raw material components are ground to a raw meal, the raw meal is burned to clinker in a combustion plant ( 2 ) and finally the clinker is ground together with further inter-grinding materials. Moreover, the mineralogical and/or chemical composition of the raw meal and/or the clinker is analysed, at least two separate raw meal silos/clinker silos ( 4 a to 4 h, 5 a to 5 g) are provided in each case for the raw meal and/or the clinker and are filled with raw meal/clinker of different mineralogical and/or chemical composition. Furthermore the composition of the raw meal to be burned and/or of the clinker to be ground is fixed by controlled extraction as a function of the analysed composition of the raw meal/clinker from one or a plurality of raw meal silos/clinker silos.
