<p>The invention relates to an apparatus for preprocessing and subsequently conveying or plasticizing plastics, comprising a container (1) with a mixing and/or comminuting tool (3) that can rotate about a rotational axis (10), wherein an opening (8) is formed in a lateral wall (9) through which the plastic material can be discharged and a conveyor (5) is provided with a screw (6) rotating in a housing (16). The invention is characterized in that the imaginary extension of the longitudinal axis (15) of the conveyor (5) passes by the rotational axis (10) counter the conveying direction (17), wherein the longitudinal axis (15) is on the outlet side offset by a distance (18) in relation to the radial (11) that is parallel to the longitudinal axis (15). A pocket (100) is formed in the wall section (105) of the housing (16), which directly adjoins the feed opening (80) in the conveying direction (17) and completely surrounds the screw (6), wherein said pocket extends in the conveying direction (17), starting with the edge (20') of the feed opening (80), situated downstream, over a length (L) of 0.8 d≤L≤9 d, d being the outer diameter or diameter of the envelope curve of the screw (6) in the wall section (105).</p> |
