Beschreibung
Zusammenfassung:	The invention relates to an apparatus for the pretreatment and subsequent conveying or plastification of plastics, with a container (1) with a mixing and/or comminution implement (3) that is rotatable around an axis (10) of rotation, wherein, in a side wall (9), an aperture (8) is formed, through which the plastics material can be removed, a conveyor (5) being provided, with a screw (6) rotating in a housing (16). The invention is characterized in that the imaginary continuation of the longitudinal axis (15) of the conveyor (5) in a direction opposite to the direction (17) of conveying passes the axis (10) of rotation, there being, on the outflow side, an offset distance (18) between the longitudinal axis (15) and the radius (11) that is parallel to the longitudinal axis (15), and in that the L/D ratio of the screw (6) is >= 7, and in that the setting angle (.gamma.) of the radially outermost mixing and/or comminution implement (3), closest to the base, complies with the following relationship: .gamma. = .kappa. * d + .KAPPA., where d is the diameter of the screw (6) in mm, .KAPPA. is a factor in the range from 15 to 35, .kappa. is a factor in the range from 0.08 to 0.2. 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 (5) présentant une 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) étant décalé côté écoulement, de l'ordre d'un écart (18), par rapport à la radiale (11) parallèle à l'axe longitudinal (15), le rapport L/D de la vis (6) est = 7 et l'angle d'attaque (?) de l'outil de mélange et/ou de broyage (3) radialement extérieur, le plus proche de la base, obéit à la relation suivante: ? = k * d + K, d étant le diamètre de la vis (6) en mm, K étant un facteur compris entre 15 et 35 et k étant un facteur compris entre 0,08 et 0,2.
