Title (EN) SYSTEM AND METHOD FOR HEAT TREATMENT OF GRANULAR AND LUMPY MATERIAL
(FR) INSTALLATION ET PROCÉDÉ DE TRAITEMENT THERMIQUE DE MATIÈRES GRANULAIRES ET EN MORCEAUX
(DE) ANLAGE UND VERFAHREN ZUR WÄRMEBEHANDLUNG VON KÖRNIGEM UND STÜCKIGEM MATERIAL
Abstract:
(EN) The system according to the invention for heat treatment of granular and lumpy material, particularly ferronickel ore, has a rotary kiln for the preliminary reduction of the material and an electric kiln for melting of the pre-reduced material. There is a screening device for separating oversized particles between the rotary kiln and electric kiln followed by a crusher for the comminution of the oversized particles.
(FR) L'invention concerne une installation de traitement thermique de matières granulaires et en morceaux, notamment de minerai de ferronickel, comportant un four rotatif pour la pré-réduction de la matière et un four électrique pour la fusion de la matière pré-réduite. Entre le four rotatif et le four électrique sont disposés un dispositif tamis pour la séparation de déclassés supérieurs puis un broyeur pour le broyage des déclassés supérieurs.
(DE) Die erfindungsgemäße Anlage zur Wärmebehandlung von körnigem und stückigem Material, insbesondere von Ferronickelerz, weist einen Drehrohrofen zur Vorreduktion des Materials und einem Elektroofen zum Schmelzen des vorreduzierten Materials auf. Zwischen Drehrohrofen und Elektroofen sind zunächst eine Siebeinrichtung zur Abtrennung von Überkorn und anschließend ein Brecher zur Zerkleinerung des Überkorns angeordnet.
