Abstract
A center plate for a rotor in a pulp refiner is described in which the center plate is provided with a plurality of first wings for directing pulp flowing onto the center portion of the center plate towards the periphery of the center plate, each of the first wings comprising an arc-shaped protrusion extending between a corresponding first point and a corresponding second point on the surface of the center plate, the first point being displaced from the center portion of the center plate and the second point being disposed further from said center portion of the center plate then the first point, the first wings having an arc shape that yields a larger pulp feeding angle then that of a circular arc intersecting the center portion of the center plate and ending in the same corresponding second point, and the second point of each of the first wings lies on the periphery of the center plate.
