ABSTRACT:
A beater bar capable of being acted upon on one side for impactor rotors and insertable form-fittedly into circumferential slots of the rotors has a bend with an elongate cross-section, a bearing surface heldable counter to a centrifugal force of the rotating rotors against a bearing surface of the rotors, a supporting surface engageable with an undercut in the circumferential slot; a piece which holds the beater bar in engagement with the undercut in an circumferential slot, the bend being arcuate, and a center of rotation of a smaller radius of an arc of the bearing surfaces being at a considerable distance from a center of rotation of a larger radius of an arc of the supporting surface, so that the two centers of rotation run in a line extending approximately parallel to a beating surface, the bearing surfaces being at an obtuse angle to one another in a prolongation of the smaller arc.
