A apparatus(10) for processing feed stock material into molten or semi-molten state. The apparatus (10) includes a barrel (12), defining an interior surface, an inlet (18), for receiving the feed stock material and an outlet (20) discharging the material. The sidewall of the barrel (12) comprises three layers, referred to as the shell (62), an intermediate layer (64) and a liner (66). The intermediate layer (64) is disposed between the shell (62) and the liner(66) is formed of a material softer than the materials forming the shell (62) and the liner (66).The presence of the intermediate layer (64) minimizes the thermal gradient along the thickness of the barrel (12).

L'invention concerne un appareil (10) destiné au traitement de matériaux de charge à l'état fondu ou semi-fondu. Cet appareil (10) comprend un baril (12) définissant une surface interne, une entrée (18), permettant de recevoir le matériau de charge et une sortie (20) permettant de décharger ledit matériau. La paroi latérale du baril (12) comprend trois couches, respectivement une enveloppe (62), une couche intermédiaire (64) et un isolant (66). La couche intermédiaire (64) est placée entre l'enveloppe (62) et l'isolant (66) et est fabriquée à partir d'un matériau plus mou que les matériaux formant l'enveloppe (62) et l'isolant (66). La présence de la couche intermédiaire (64) minimise le gradient thermique le long de l'épaisseur du baril (12).
