Abstract: The invention relates to a device (1) for extruding thermoplastic material, having an extruder housing (22) in which an extruder screw (22) driven by a drive device (23) is supported rotatably about the axis thereof, said housing comprising an intake opening (24) to which a plastic material feeder (3) is connected, said feeder comprising at least one air inlet opening (36), wherein the extruder housing (22) comprises at least one vapor outlet opening (41) upstream of the intake opening (24) and an air/vapor path (28) is defined from the intake opening (24) to the vapor outlet opening (41).

Abstract: The invention relates to a device (1) for reducing thermal plastic goods (2), comprising a container (3) for receiving the in particular loosely packed plastic goods (2) and a reducing device (4) projecting into the container or arranged therein for reducing the plastic goods and the conveyance thereof to a discharge opening (5), characterized by air inlets (6) in the region of the reducing device and air outlets (7) in the container wall (8).

Abstract: A system for the delivery of bulk material, in particular a free-flowing bulk material such as, e.g., plastic granules, comprises a discharge base (7) having recesses (8), with a discharge opening (9) being formed in each of the recesses (8), and a cover plate (11) which is arranged on the outflow side of the discharge base (7) at a distance (h) from the same, with the cover plate (11) having openings (12) which are arranged essentially in the same pattern as the discharge openings (9) of the discharge base (7). The cover plate (11) and the discharge base (7) are movable relative to each other between an opened condition in which the discharge openings (9) of the discharge base (7) and the openings (12) of the cover plate (11) overlap each other at least partially, preferably being congruent, and a closed condition in which the discharge openings (9) of the discharge base (7) exhibit such an axial offset (s) from the openings (12) of the cover plate (11) that no overlap is produced.

Abstract: A device for granulating plastic melts comprises a granulating head (2) to which a perforated plate (3) provided with melt-discharge openings (10) is attached, which openings are swept by rotating knives (4). The perforated plate (3) is enclosed by a granulating housing (1) which is provided with at least one housing inlet (7) through which a cooling and transport medium (C), preferably water or air, can be supplied to the interior of the granulating housing (1), the cooling and transport medium (C) flowing with a motion component along the inner wall of the granulating housing (1) from the granulating head (2) toward a housing outlet (8) which is arranged in the end region of the granulating housing (1) opposite to the granulating head (2) and through which the cooling and transport medium (C) can be discharged along with the granules (G) produced.
