主权项

1. A system for processing objects containing flammable particles, comprising:
a shredder unit having:
a shredder with a shredding chamber for receiving objects containing flammable particles, and one or more blades in the shredding chamber for shredding the objects into a plurality of shredded fragments;a cooling system for providing a coolant on or around an external surface of the shredder during operation; andan injection system for injecting a non-flammable gas into the shredding chamber during operation; and a particle removal unit having:
a vibration unit with a base portion for holding the plurality of shredded fragments, the base portion having a plurality of apertures through which the flammable particles can pass under gravity, wherein the vibration unit vibrates during operation so as to remove at least some of the flammable particles from the plurality of shredded fragments; anda suction unit having a suction channel with an opening, and a suction motor for creating suction pressure in the suction channel; wherein during operation suction pressure created by the suction motor removes at least some of the flammable particles from the plurality of shredded fragments adjacent the opening.
