1. A fragmentation system for electrodynamic fragmentation of material, the fragmentation system comprising:
an inlet and at least one outlet for the material;
a transport path leading from said inlet to said at least one outlet for transporting the material along said transport path in a transport direction;
a plurality of fractionation sections in a sequential arrangement along the transport path;
each fractionation section of said plurality of fractionation sections including a high-voltage pulse source with at least one first electrode and at least one second electrode for generating a high-voltage discharge;
the high voltage pulse source of each fractionation section operating with operating parameters including at least one of a voltage and a power;
a magnitude of the operating parameters of the high-voltage pulse source of each fractionation section in the sequential arrangement along the transport path being less than a magnitude of the operating parameters of any preceding fractionation sections in the sequential arrangement along the transport path from the inlet; and
a selection means for selectively extracting the material on said transport path in order to channel the material and/or fragments of the material having a diameter smaller than a predetermined diameter past at least one portion of one of said plurality of fractionation sections.
