Abstract
(EN)
The present invention provides a method and system for manufacturing cement wherein ground particles of cement and calcium sulfate are subjected to infrared sensors, laser sensors, or both, so that emanated, irradiated, transmitted, and/or absorbed energy having wavelengths principally within the range of 700 nanometers to 1 millimeter can be monitored and compared to stored data previously obtained from ground cement and sulfate particles and preferably correlated with stored strength, calorimetric, or other data values, such that adjustments can be made to the mill processing conditions, such as the form or amounts of calcium sulfate (e.g., gypsum, plaster, anhydride), or cement additive levels. The strength and other properties of cement can be thus adjusted, and its quality can be more uniform.
(FR)
La présente invention concerne un procédé et un système de fabrication de ciment dans lequel des particules broyées de ciment et de sulfate de calcium sont soumises à des capteurs infrarouges, des capteurs laser, ou les deux, de sorte que l'énergie, irradiée, transmise, et/ou absorbée ayant des longueurs d'onde principalement comprises dans la plage de 700 nanomètres à 1 millimètre peut être controlée et comparée à des données stockées précédemment obtenues à partir de particules de ciment et de sulfate broyées et de préférence corrélées avec les valeurs de résistance, de calorimétrie ou d'autres données stockées,, de telle sorte que des ajustements peuvent être apportés aux conditions de traitement du broyeur, telles que la forme ou les quantités de sulfate de calcium (par exemple, le gypse, plâtre, anhydride), ou les niveaux d'additifs de ciment. La résistance et autres propriétés du ciment peuvent être ainsi ajustées, et sa qualité peut être plus uniforme.
