Device for processing plastic material

A device for treating plastic materials, comprising:

• at least one receiving container (1) in which at least one mixing and/or comminution tool (3) which is rotatable around a rotational axis (10) is disposed for mixing said plastic materials, and
• at least one conveyor (5) for transporting the plastic materials out of the receiving container (1), said conveyor (5) having at least one screw (6) rotating in a housing (16) and, said conveyor (5) being connected at its material input side to the interior of the receiving container (1) via an opening (8) formed in a lateral wall (9) of said receiving container (1), wherein the central longitudinal axis (15) of the conveyor (5) and of the screw (6) extends in a direction opposite the conveying direction (17) of the conveyor (5) and past the rotational axis (10) of the receiving container (1) without intersecting it, said central longitudinal axis (15) of the conveyor (5) and the screw (6) being offset in the rotational and moving direction (12) of the mixing and/or comminution tool (3) at a discharge side by a distance (18) from a radial line (11) of the container (1), which is parallel to the longitudinal axis (15) and, in the conveying direction (17) of the conveyor (5), extends outwards from the rotational axis (10) of said mixing and/or comminution (3) tool,
• wherein the conveyor (5) is connected to the receiving container (1) such that a scalar product of a direction vector (19) of the mixing and/or comminution tool (3) which is oriented tangential with respect to the circle of rotation of the mixing and/or comminution tool (3) and normal with respect to a radial ray (11) of the receiving container (1), and which points in the rotation or movement direction (12) of the mixing and/or comminution tool (3), and a direction vector (17) of the conveyance direction of the conveyor (5), is zero or negative at each point of the opening (8).
