Abstract: A shredder includes a rotor supporting a plurality of multi-point cutters that mesh with a counter-knife having generally V-shaped grooves. Each cutter has at least one corner defined by an intersection between two contiguous side faces of the body of the cutter. The corner defines a plurality of cutting points spaced apart along a first direction. The cutters are mounted on the outer peripheral surface of the rotor such that the first direction of each cutter is substantially tangent to the outer peripheral surface, and such that the corners of the cutters mesh with respective V-shaped grooves in the counter-knife as the rotor rotates about its axis. The multiple points of each cutter encounter and mesh with the groove in the counter-knife in a sequential fashion.

Abstract: A mobile shredder comprises a truck having a truck body defining an enclosure and including a partition in the enclosure that divides a storage volume from the remainder of the enclosure for storage of shredded material in the storage volume, a single-shaft rotary shredder mounted in the enclosure outside the storage volume, the rotary shredder comprising a rotor having cutters rigidly mounted thereon, a bin lift and dump mechanism operable to transport material to be shredded from outside to inside the enclosure so as to deliver material to the rotary shredder, and a discharge conveyor operable to transport shredded material from the rotary shredder through the partition to the storage volume. The floor of the storage volume can comprise a walking floor, and the enclosure can have rear doors that are openable to allow shredded material to be discharged through the open rear doors when the walking floor is operated.
