Abstract
A shredder apparatus and method for shredding wet chip materials in which the shredder utilizes a shredder mechanism having a shaft attached to a frame, a bearing assembly disposed on the shaft, and a rotatable rotor disposed on the bearing assembly. First shredder members are attached to and rotatable with the rotor, and cooperate with second shredder members attached to the frame to shred wet chip materials fed into the shredder apparatus.
Claims34
A shredder apparatus for shredding wet chip materials into granular wet chips, said apparatus comprising:
- a frame;
- a shaft fixedly attached to said frame, said shaft having a length and a first end and a second end;
- a bearing assembly disposed on said shaft and located inwardly from said shaft ends;
- a rotatable rotor having a cylindrical wall and a first end and second end and a length less than said shaft length, said rotor being disposed on said bearing assembly between said rotor ends;
- a plurality of spaced first shredder members attached to and rotatable with said rotor;
- a plurality of spaced second shredder members attached to said frame and mounted on but free from rotation with said rotor, said second shredder members being positioned relative to said first shredder members whereby a first shredder member and a second shredder member are adapted to cooperate to shred wet chips;
- first and second seal members, said first seal member being disposed on said shaft inwardly of said first shaft end and said second seal member being disposed on said shaft inwardly of said second shaft end to substantially enclose and seal said bearing assembly between said rotor and said shaft;
- and,
- a drive assembly for rotating said rotor while said shaft remains in a fixed position whereby upon actuation of said drive assembly, said rotor will rotate causing said first and second shredder members to cooperate to shred wet chip material in said shredder apparatus.

A shredder apparatus for shredding wet chip materials, said apparatus comprising:
- a frame;
- a shaft having first and second shaft ends and a length;
- said shaft attached to said frame at the location of said first and second shaft ends;
- a bearing assembly seated on said shaft;
- a rotatable cylindrical shaped rotor having a first end and a second end and a length less than said shaft length, said rotor being disposed over said shaft and seated on said bearing assembly;
- a first seal member disposed on said shaft and located at said first rotor end;
- a second seal member disposed on said shaft and located at said second rotor end;
- said seal members and rotor substantially enclosing and sealing said bearing assembly between said shaft and rotor;
- a drive assembly for rotating said rotor while said shaft remains in a fixed position;
- a plurality of spaced first shredder members attached to said rotatable rotor for rotation with said rotor;
- and,
- a plurality of spaced second shredder members attached to said frame and mounted on but free from rotation with said rotor, said first and second shredder members being adapted to cooperate to shred wet chip material when said rotor is rotated.

A shredder apparatus for shredding wet chip materials into granular wet chips, said apparatus comprising:
- a frame;
- a shaft attached to said frame, said shaft having a first end and a second end;
- a bearing assembly disposed on said shaft;
- a rotatable rotor having a cylindrically shaped closed wall and a first end and second end, said rotor being disposed on said bearing assembly;
- a plurality of spaced first shredder members attached to and rotatable with said rotor;
- a plurality of spaced second shredder members attached to said frame and mounted on but free from rotation with said rotor, said second shredder members being positioned relative to said first shredder members whereby a first shredder member and a second shredder member are adapted to cooperate to shred wet chips;
- a seal assembly disposed between said rotor and said shaft for substantially enclosing and sealing said bearing assembly between said shaft and rotor;
- and
- a drive assembly for rotating said rotor while said shaft remains in a fixed position whereby, upon actuation of said drive assembly, said rotor will rotate causing said first and second shredder members to cooperate to shred wet chip material in said shredder apparatus.
