Beschreibung
Zusammenfassung:	The invention relates to an apparatus for the pretreatment and subsequent conveying or plastification of plastics, with a container with a mixing and/or comminution implement that is rotatable around an axis of rotation, wherein, in a side wall, an aperture is formed, through which the plastics material can be removed, a multiscrew conveyor being provided, with at least two screws rotating in a housing. The invention is characterized in that the imaginary continuation of the longitudinal axis of the conveyor in a direction opposite to the direction of conveying passes the axis of rotation, where, on the outflow side, there is an offset distance between the longitudinal axis of the screw closest to the container and the radius that is parallel to the longitudinal axis, and in that the two screws closest to the intake aperture are counter-rotating relative to one another. L'invention concerne un dispositif de pré-traitement et de transport ou malaxage consécutif de plastiques, comportant une cuve (1) présentant un outil de mélange et/ou de broyage (3) tournant autour d'un axe de rotation (10). Une paroi latérale (9) présente une ouverture (8) à travers laquelle le matériau plastique peut être distribué, le dispositif comportant également un transporteur à plusieurs vis (5) présentant au moins deux vis (6) tournant dans un boîtier (16). L'invention est caractérisée en ce que le prolongement imaginaire de l'axe longitudinal (15) du transporteur (5), dans le sens opposé au sens de transport (17), s'étend à côté de l'axe de rotation (10), l'axe longitudinal (15) de la vis (6) la plus proche de la cuve (1) étant décalé côté écoulement, de l'ordre d'un écart (18), par rapport à la radiale (11) parallèle à l'axe longitudinal (15), et les deux vis (6) les plus proches de l'ouverture d'entrée (80) sont contrarotatives.
