ABSTRACT:
Replaceable protective means for protecting an end disc of a rotor shredder from excessive wear includes a protective cap of hardened, wear resistant metal, and at least two pins and washers of readily weldable metal. The protective cap has a U-shaped channel for receiving a curved portion of the periphery of the end disc. The opposed walls of the U-shaped channel each have at least one pair of pin-receiving openings and the openings in each wall are aligned with those in the opposed wall. When the cap is positioned in place on the end disc with the pin receiving openings in the opposed walls of the cap aligned with openings which extend through the end disc, the pins which have enlarged heads at one end which are larger than the openings in the disc can be inserted into the aligned openings and secured in place by welding a washer which also is larger in diameter than the openings in the disc to the other end of each of the pins. The protective cap is thus retained in place on the end disc by the welded pin and washer combinations which are not directly attached to either the cap or the end disc. The protective cap may be provided with a dependent skirt so that it protects not only the edge or periphery of the end disc, but also interior areas which are subject to wear.
