ABREGE DU CONTENU TECHNIQUE DE L'INVENTION
INSTALLATION POUR LA FRAGMENTATION DES
REBUTS ET DECHETS CARBONES D'UNE USINE DE
PRODUCTION D'ALUMINIUM
F C B
L'invention concerne les usines de production d'aluminium dans lesquelles les
mégots d'anodes usées et les anodes entières rebutées doivent être fragmentées, en vue
de recyclage des produits carbonés à l'atelier de fabrication d'anodes, et où le traitement
des vieilles brasques (produits carbonés provenant de la démolition du revêtement des
parois et du fond des cuves d'électrolyse de l'alumine) exige une réduction préalable des
brasques en morceaux dont la taille n'excède pas quelques millimètres.
Le but de l'invention est de permettre l'utilisation de la même installation pour
la fragmentation des mégots d'anodes et des anodes rebutées, d'une part, et des vieilles
brasques, d'autre part, moyennant des modifications du matériel peu importantes et
réalisables rapidement.
L'installation objet de l'invention est caractérisée en ce qu'elle est constituée
essentiellement par un concasseur à mâchoires (10) et un broyeur autogène ou semi-
autogène (12) comportant des ouvertures périphériques (30) équipées de grilles à orifices
calibrés et une ouverture centrale (31) pour l'évacuation pneumatique de la fraction fine
des produits broyés, et en ce que des moyens sont prévus pour obturer les ouvertures
périphériques du broyeur.
