Abstract (en)

[origin: US4714207A] An impact bar - adapted to assume an installed state in which it is mounted in a rotor of a comminuting machine - has a length extending generally radially as viewed relative to the rotary axis, a leading side and a trailing side as viewed relative to a direction of rotation, and a cross-sectional area taken along a sectional plane extending parallel to a plane of rotation. The cross-sectional area is curved in a generally C shape open towards the leading side and is symmetrical relative to a symmetry plane being generally perpendicular to the bar length. The cross-sectional area has a constriction lying in the symmetry plane. The trailing side is adapted to be supported against tangential forces at a location situated radially outwardly of the constriction as viewed relative to the rotary axis. The constriction is formed by a first and a second groove at the leading and trailing side. Each groove is cross-sectionally symmetrical to the symmetry plane and each has a groove bottom and lateral groove flanks constituting holding faces for taking up generally radially oriented forces.
