(FR) PROCÉDÉ DE TRAITEMENT DE CENDRES VOLANTES ET INSTALLATION ET PROCÉDÉ DE PRODUCTION DE CIMENT
(DE) VERFAHREN ZUR AUFARBEITUNG VON FLUGASCHE SOWIE ANLAGE UND VERFAHREN ZUR HERSTELLUNG VON ZEMENT
Abstract:
(EN) The method according to the invention for re-processing fly ash is characterised by the milling of fly ash in a dry-operated stirred ball mill. The plant according to the invention for producing cement has at least one first milling stage, consisting of a first mill and a first air separator, for milling cement clinker, and also provides a dry-operated stirred ball mill for milling fly ash, in addition to at least one withdrawal system for the combined discharge and/or combined storage of the milled cement clinker and the milled fly ash.
(FR) Le procédé de traitement de cendres volantes de la présente invention est caractérisé par un broyage des cendres volantes dans un broyeur à boulets fonctionnant à sec. L’installation de l’invention destiné à la production de ciment comprend au moins un premier étage de broyage comprenant un premier broyeur et un premier séparateur et destiné à broyer le ciment, et prévoit en outre un broyeur à boulets fonctionnant à sec destiné à broyer les cendres volantes et au moins un dispositif d’évacuation destiné à évacuer et/ou stocker conjointement le clinker de ciment broyé et les cendres volantes broyées.
(DE) Das erfindungsgemäße Verfahren zur Aufarbeitung von Flugasche zeichnet sich durch eine Mahlung der Flugasche in einer trockenbetriebenen Rührwerkskugelmühle aus. Die erfindungsgemäße Anlage zur Herstellung von Zement weist wenigstens eine aus einer ersten Mühle und einem ersten Sichter bestehende erste Mahlstufe zur Mahlung von Zementklinker auf und sieht weiterhin eine trockenbetriebene Rührwerkskugelmühle zur Mahlung von Flugasche sowie wenigstens eine Abzugseinrichtung zum gemeinsamen Abführen und/oder zur gemeinsamen Lagerung des gemahlenen Zementklinkers und der gemahlenen Flugasche vor.
