Abstract:
1. 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 and heating and, optionally, cutting and/or softening said plastic materials, wherein the at least one mixing and/or comminution tool ( 3 ) has an extreme point located at the greatest radial distance from the rotational axis ( 10 ) and wherein the extreme point located at the greatest radial distance from the rotational axis ( 10 ) defines a bounding circle when the at least one mixing and/or comminution tool ( 3 ) is rotated about the rotational axis ( 10 ), 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 at its material input side, connected to the interior of the receiving container ( 1 ) via an opening ( 8 ) formed in a lateral wall ( 9 ) of said receiving container ( 1 ) in order to supply or feed the material into said receiving container ( 1 ), said opening ( 8 ) being disposed at the height of the mixing and/or comminution tool ( 3 ), wherein a portion of the central longitudinal axis ( 15 ) of the conveyor ( 5 ) and the screw ( 6 ) in the direction opposite the conveying direction ( 17 ) of the conveyor ( 5 ) passes the rotational axis ( 10 ) of the receiving container ( 1 ) without intersecting it, said 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 ), which is rotating past the opening ( 8 ), and of the plastic materials, which are transported past the opening ( 8 ), 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 screw ( 6 ) is outside of the bounding circle.
