ABSTRACT:
A striker assembly for attachment to the rotor lobe of a rotary hog for impact fragmentation, cutting and shearing action. The striker assembly includes a striker plate having a body portion attachable to the rotor lobe by means of screwthreaded connectors with the top portion of the striker plate extending radially beyond the rotor periphery. The striker plate has an offset ledge for receiving one or more striker bits which are clamped thereto by appropriate bolts and which include protrusions on the rear face thereof in engagement with mating recesses in the striker plate face. Each striker bit is symmetrical around a central longitudinal plane with opposed cutting edges running the length of the bit. The bit is removable and may be rotated 180.degree. allowing alternate use of the cutting edges. The bit includes forward faces adjacent the cutting edges which are disposed at an angle to the front and rear faces of the bit so as to provide an aggressive cutting edge. When mounted on the striker plate, and depending upon the orientation of the striker plate, a rake angle of 0.degree.-25.degree. is formed. In one embodiment, the striker plate is wedge shaped for disposing the cutting edges of the striker bits at an angle relative to the rotational axis of the rotor to exert a shearing action on the material before impact with an anvil.
