Device for processing material, in particular plastics material

A device for processing plastics material, comprising

• a shredding unit for shredding and optionally heating the material having a shredding housing in which a rotor body that is able to be driven in rotation about a longitudinal axis of the rotor body, is provided, which bears a multiplicity of shredding tools on a circumference of the rotor body, and having a feed opening through which the material to be shredded is able to be fed to the rotor body;
• a conveying unit, adjoining an output region of the shredding unit, having a housing and a screw, which is mounted therein and is able to be driven in rotation, for conveying and optionally compressing material output from the shredding unit, wherein the shredding unit or the rotor body is configured such that the material is able to be conveyed in an axial direction of the rotor body towards and through the output region, on a front side of the screw, and wherein the longitudinal axis of the rotor body and a longitudinal axis of the screw are oriented parallel to one another;
• and
• and an extruder, adjoining the screw, having an extruder housing and at least one extruder screw that is mounted therein and able to be driven in rotation, wherein a front-side discharge opening is formed in the housing, via which the material is able to be conveyed into an intake opening of the extruder to the extruder screw,
• wherein,
• the longitudinal axis of the screw is oriented at an angle to a central longitudinal axis of the extruder screw, the longitudinal axis of the screw and the central longitudinal axis of the extruder screw extending in X-Y axis directions,
• and the longitudinal axis of the screw is offset with respect to the longitudinal axis of the extruder screw in a Z-axis direction relative the X-Y axes directions by an offset distance in a direction of rotation of the extruder screw at or in a region of the discharge opening or the intake opening, wherein the Z-axis is orthogonal to the X-Y axes directions;
• wherein the offset distance is in a range of 0<v<R, wherein R is a radius of the extruder screw.
