ABSTRACT:
A shredder for reducing scrap materials such as scrapped automobiles to pieces of a smaller size includes a shredder housing having an inlet and an outlet, rotary hammer means positioned in said housing, cutter means, and means for rotating said hammer means to co-act with said cutter means to reduce the material to smaller pieces. The outlet is closed by a door which contains a discharge grate through which shredded pieces must pass to leave the housing. The door is normally locked, but can be opened from the outside to permit unshreddables to be readily removed from the shredder and to replace the grate when necessary. In one embodiment the outlet is located in the end wall of said housing preferably about 180.degree. from the inlet and the door contains a grate which is comprised of a plurality of grate segments.
