Abstract:
A tire chopping apparatus for chopping a tire carcass into smaller tire fragments and comprising:a) a frame; b) an elongated rotor assembly journaled on said frame to rotate about a rotor axis and including a plurality of chopper discs spaced axially therealong, each chopper disc including a set of outwardly extending and circumferentially spaced rotor teeth; c) a motor drivingly engaged with said rotor assembly and selectively operable to cause rotation of said rotor assembly; d) an elongated shear bar assembly connected to said frame, extending parallel to said rotor assembly, and positioned in spaced relation thereto, said shear bar assembly including a plurality of shear teeth so positioned therealong relative to the sets of rotor teeth that said rotor teeth cyclically revolve into respective shear relationships with said shear teeth; and e) a plurality of guards extending outwardly from said shear bar assembly between adjacent sets of said rotor teeth toward said rotor mandrel, said guards being spaced apart in such a manner as to limit the size of objects passing between said rotor assembly and said shear bar assembly.
