Rotor disk
First Claim
1. A rotor disk configured to be installed in a receiving container for the treatment of polymers, comprising:
- a disk body shaped substantially as a disk and rotatable about an axis thereof, the disk body comprising an upper face and a lower face, wherein the upper face is configured for either or both of a mixing tool and a comminuting tool to be provided on the upper face; and
a plurality of conveying ribs disposed on the lower face of the disk body, wherein the ribs extend from a central region of the disk body toward an outer edge of the disk body, wherein said conveying ribs are configured to convey polymer particles toward the edge of the disk body during rotation of the disk body about the axis, wherein the conveying ribs are curved concavely in a direction of rotation of the rotor disk, wherein a particular conveying rib of the plurality of conveying ribs has a first point at the central region of the particular conveying rib, wherein the particular conveying rib has a second point farther from the axis than the first point, wherein the particular conveying rib at the first point protrudes from the disk body by a first distance, wherein the particular conveying rib at the second point protrudes from the disk body by a second distance, wherein the second distance is greater than the first distance, and wherein the second point is intersected by a line tangent to the particular conveying rib at the second point, wherein the line is oriented at an angle α
between 0° and
25°
with respect to the edge of the disk body,wherein the disk body extends from a plurality of centermost portions of centermost conveying ribs toward the axis.

Abstract
The invention at hand relates to a rotor disk (1) to be inserted into a receptacle (2) for the treatment of polymers, having a disk body (3) on whose top side (4) mixing and/or comminuting tools (5) are providable and on whose opposite underside (6) a number of conveying ribs (7) extending from the interior to the exterior are provided with which during operation polymer particles are transportable towards the exterior or, respectively, that during operation exert a force directed from the center (8) of the rotor disk (1) towards the exterior on the polymer particles grasped by the conveying ribs (7). In accordance with the invention it is provided that the conveying ribs (7) are curved concavely in the direction of rotation or, respectively, of movement.
