Abstract:
1. A rotor disk for installation in a receiving container for the treatment of polymers, comprising: a disc body configured to provide on an upper face of the disc body at least one era mixing or a comminuting tool and configured to provide on a lower face of the disc body a number of conveying ribs which extend from a center of the disc body toward a circumference of the disc body, wherein said conveying ribs are concavely curved in a rotational or a running direction, further wherein said conveying ribs are configured to at least one of convey polymer particles toward a circumference of the disc body during operation or exert a force directed outward from the center of the rotor disk on the polymer particles caught by the conveying ribs during operation, wherein the thickness of the disk body in an inner section is constant, and starting from a distance from the center of the rotor disk of 60% to 70% of the radius of the disk body is reduced towards the circumference of the disk body, and further wherein the disk body decreases in thickness toward the circumference of the disc body in the same proportion as the conveying ribs increase in height toward the circumference of the disc body such that the overall thickness of the rotor disk is equal and constant over the radius of the disc body.
