Abstract

A rotor disc for accelerating and projecting particles radially outwards off the disc toward an encircling impact element includes a rotatable disc base having radial channels for guiding particles radially outwards. The channels are formed of side walls fixed to the disc base with side faces on opposite sides of each channel. The corresponding side faces of each pair of sidewalls are arranged essentially parallel and have, in each pair of opposed faces, at least a first face which a radial chamfer having at least a first and a second chamfer face which are angled to form a groove disposed above the disc base for guiding the particles.
