ABSTRACT:
The invention provides an impact member for assembly with a rotor arranged in a comminuter used for the size reduction of feed material. The impact member, disposed radially about the rotor, comprises a carrier and a replaceable impact plate both configured for complementary registration so as to be cantilevered from the carrier and to provide an essentially locking arrangement to withstand the impact forces without coming loose. The carrier has a forwardly disposed open recess or channel with first and second facings intersecting in an axial direction relative to the horizontal axis of the rotor, and defining an acute angle relative to the radial plane of the rotor. The first facing is oriented in the general direction of rotation of the rotor and terminates with a longitudinally extending marginal edge disposed axially relative to the horizontal axis of the rotor. The replaceable impact plate is configured as a substantially non-right angled parallelogram as viewed in transverse profile, and has intersecting sides for complementary registration with the first and second facings of the recess. Thus, when the replaceable impact plate is arranged in the recess with side walls matching the facings of the recess, the impact plate is cantilevered from the recess so as to project outwardly from the marginal edge. The impact plate includes a leading edge oriented in the general direction of rotation of the rotor. This complementary registration of the two members essentially locks the replaceable impact plate in the recess so as to withstand the resulting impact forces occurring during operation of the machine. A suitable fastening element, such as a relatively low torque bolt, holds the wear resistant member in place on the carrier.
