ABSTRACT:
A rotor which is to be used in an impact crusher has a set of coaxial discs with radially inwardly extending peripheral recesses for elongated beater bars which are parallel to the rotor axis and each of which extends into a discrete recess of each disc. The beater bars have male or female detent elements which cooperate with complementary female or male detent elements of the discs at the rear sides of the beater bars to prevent radially outward movements of the beater bars in actual use of the rotor. The front sides of the beater bars are engaged by wedges which are biased radially outwardly against the beater bars and against the respective discs by fluid-operated thrust elements in the recesses of the discs. Each thrust element has a piston rod which bears against the respective wedge and urges the wedge radially outwardly in the respective recess, and each thrust element reacts against an elongated rail which is installed in the deepmost portions of a set of aligned recesses of the discs. The thrust elements receive pressurized fluid by way of an elongated bore and radially extending ports in the rails which have each a valved connecting member at one axial end. The connecting members are connected to the respective rails by way of a channeled sleeve which surrounds the rotor shaft where it passes the housing wall of the impact crusher, the sleeve shares the rotating movements of the discs.
