A horizontal mixer for mixing and processing materials includes a horizontally disposed mixing chamber and an elongated rotatable mixing shaft extending longitudinally through the chamber. The drive apparatus is coupled lo a drive of the mixing shaft to rotate the shaft and mix material placed in the chamber. A stub end of the shaft has a bearing portion extending through an end wall of the chamber opposite the drive end of the shaft. The bearing portion engages a sleeve bearing which is operable for rotatably supporting the stub end proximate the end wall opening. A sealing shroud is coupled proximate the sleeve bearing and covers an outer portion of the shaft stub end. A static shroud seal is coupled with the sealing shroud at an interface between the shroud and the sleeve bearing. The static shroud is maintained out of direct contact with the rotatable shaft stub end. The sealing shroud and static shroud effectively isolate the shaft stub such that leakage between the chamber and the outside atmosphere is generally prevented.
Mélangeur horizontal pour le brassage et le conditionnement de matières, comportant une chambre de mélange disposée dans l'axe horizontal et un arbre mélangeur rotatif traversant la chambre de mélange. L'arbre de mélange est relié à un mécanisme d'entraînement. L'extrémité non entraînée de l'arbre est pourvue d'un palier à coussinets qui traverse la paroi d'extrémité de la chambre de mélange et permet la libre rotation de l'arbre. Un épaulement dynamique, fixé à l'arbre près du palier à coussinets, se prolonge sur la portion extérieure de l'arbre. Un épaulement statique est couplé à l'épaulement dynamique, à son interface avec le palier. L'épaulement statique ne vient jamais en contact direct avec l'extrémité de l'arbre en rotation. Les deux épaulements assurent généralement l'isolation de l'arbre et l'étanchéité de la chambre de mélange par rapport à l'air extérieur.
