ABSTRACT:
Feeding structure for tire shredding apparatus comprises a set of studded rollers defining a feed mouth opening into a feed throat that leads into the tire shredding mechanism. Forwardly placed lower and upper rolls rotate at different speeds, the upper faster than the lower and preferably having its studs configured to provide sharp points for penetrating into the tire and positively advancing it rearwardly toward the shredding mechanism. An endless conveyor carries individual tires sequentially into the feed mouth flatwise and the throat preferably slopes downwardly to present each tire to, but tilted backwardly from, the shredding mechanism. The rolls are mounted in a protective cover for the shredding mechanism, which cover is pivoted, so as to rise and fall in accordance with tire thickness, and is mounted on shock absorbers and preferably in supplemental, pivot supporting brackets.
