Treatment system for plastic material

A processing plant (1) for plastics material, in particular for the processing of thermoplastic plastics material for the recycling thereof, comprising

• a feed device (4),
• a processing unit (2) having a comminuting device (5), a preferredly spirally configured conveying device (6), a tubularly configured housing (7), and having at least one drive means for the comminuting device (5) and for the conveying device (6),
• whereby the comminuting device (5) and the conveying device (6) adjoining the comminuting device (5) in the direction of conveyance are accommodated in the axial direction, and rotatably mounted, in the tubularly configured housing (7), and
• whereby the conveying device (6) defines a first conveying section (8) having a first longitudinal axis (9), and
• whereby the housing (7) has, in the region of the comminuting device (5), at least one feed opening open toward the feed device (4) and, in an end region of the conveying section (8) of the conveying device (6), a discharge opening (10),
• a plasticizing device (3) having at least one extruder screw (11), accommodated in an extruder housing (12), and a further drive means for the at least one extruder screw (11), and the at least one extruder screw (11) defines a further longitudinal axis (13) and a further conveying section (14),
• whereby, viewed in the direction of conveyance, the plasticizing device (3) is arranged downstream of the processing unit (2), and
• whereby a fill opening (15) is arranged in the extruder housing (12), and the fill opening (15) and the discharge opening (10) arranged in the housing (7) are arranged directly adjoining each other, form a common connecting opening and are fluidically connected to each other, and
• whereby, with respect to a projection onto a horizontal plane, the first conveying section (8) of the conveying device (6), with its first longitudinal axis (9), and the further conveying section (14) of the at least one extruder screw (11), with its further longitudinal axis (13), are oriented such that they intersect in the region of the discharge opening (10) and the fill opening (15),
• wherein the preferredly spirally configured conveying device (6) has, in the region of the discharge opening (10) from the housing (7), a direction of circulation which runs, with respect to the direction of conveyance of the at least one extruder screw (11), in the direction opposite thereto.
