Un four rotatif \u00e0 bauxite est principalement un four rotatif destin\u00e9 au traitement et \u00e0 la pr\u00e9paration de la bauxite. Il se compose d'une partie rotative, d'une partie de support, d'un dispositif de transmission, d'un couvercle de t\u00eate de four, d'un syst\u00e8me d'\u00e9tanch\u00e9it\u00e9 t\u00eate\/queue de four et d'un dispositif de combustion. La bauxite est une forme d'alumine hydrat\u00e9e, d'une duret\u00e9 de 1 \u00e0 3, opaque et tendre. Elle est largement utilis\u00e9e dans l'industrie de la fusion de l'aluminium et l'industrie de la fabrication de pr\u00e9cision.<\/p>\n\n\n

Caract\u00e9ristiques remarquables du four rotatif \u00e0 bauxite<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

1. Faible consommation \u00e9nerg\u00e9tique, permettant de r\u00e9duire la consommation de charbon unitaire de 40% par rapport aux convertisseurs \u00e0 d\u00f4me sph\u00e9rique ordinaires, avec une bonne stabilit\u00e9 et un fort avantage de prix sur le march\u00e9 ;<\/p>\n\n\n\n

2. Fonctionnement simple et fiable, n\u00e9cessitant peu de personnel et un proc\u00e9d\u00e9 stable ;<\/p>\n\n\n\n

3. Faible pollution environnementale, maintenance r\u00e9duite et taux de fonctionnement \u00e9lev\u00e9 ;<\/p>\n\n\n\n

4. Peut \u00eatre adapt\u00e9 \u00e0 plusieurs types de combustibles tels que le gaz, le charbon pulv\u00e9ris\u00e9 et le fioul.<\/p>\n\n\n

Principe de fonctionnement du four rotatif \u00e0 bauxite<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

La mati\u00e8re entre dans le four par l'extr\u00e9mit\u00e9 arri\u00e8re (l'extr\u00e9mit\u00e9 sup\u00e9rieure du cylindre) pour la calcination. En raison de l'inclinaison et de la rotation lente du cylindre, la mati\u00e8re effectue \u00e0 la fois un mouvement de roulement dans le sens circonf\u00e9rentiel et un d\u00e9placement axial (de l'extr\u00e9mit\u00e9 sup\u00e9rieure vers l'extr\u00e9mit\u00e9 inf\u00e9rieure). Pour poursuivre le processus, la mati\u00e8re premi\u00e8re entre dans le refroidisseur via la hotte du four pour y \u00eatre refroidie.<\/p>\n\n\n
