An extruded polymer composite may include a polymer matrix. An extruded polymer composite may include and a filler content greater than about 65 wt % homogenously distributed about the polymer matrix.

Disclosed is a device for processing plastic materials, having a shredding unit, a conveying unit having a screw (7), and an extruder, having at least one extruder screw (11), adjoining the screw, wherein the central longitudinal axis (3) of the screw (7) is oriented at an angle to the central longitudinal axis (10) of the extruder screw (11), in particular at an angle of 80 to 100, preferably 90, and the longitudinal axis (3) of the screw (7) is offset with respect to the longitudinal axis (10) of the extruder screw (11) by an offset (v) in the direction of the direction of rotation (12) of the extruder screw (11) at or in the region of the discharge opening (8) or the intake opening (16) of the conveying unit.

An extruder-mixer has a stator and a rotor which is arranged coaxially with respect to the stator. The rotor is rotatably supported with respect to the stator. The stator is at least partially arranged inside a volume defined by the rotor. The rotor has a rotor cage having a large number of apertures. The apertures are configured to be elongate in a longitudinal direction and the longitudinal direction thereof extends in each case in a skewed manner with respect to a rotation axis of the rotor.
