Claim 14:
15. A method for electrodynamic fragmentation of material, which comprises the steps of:
transporting the material from an inlet toward an outlet along a transport path;
providing 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, the high-voltage pulse source of each fractionation section operating with operating parameters including at least one of a voltage and a power, and 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;
generating, via the high-voltage pulse source of each fractionation section of the plurality of fractionation sections, a high-voltage discharge between the at least one first electrode and the at least one second electrode; and
channeling the material and/or fragments of the material having a diameter smaller than a minimum diameter past at least one portion of one of the plurality of fractionation sections.
