Abstract

A fragmentation system for electrodynamic fragmentation of material contains a feed and an outlet for transporting material along a transport path in a transport direction. At least one high-voltage pulse source is provided, each of the high-voltage pulse sources contains at least one first electrode and at least one second electrode for generating a high-voltage discharge in a discharge chamber. The transport path has a fractionation section, and the fractionation section extends through the discharge chamber. A selection device for selectively extracting the material on the transport path is provided in order to channel material and/or fragments of the material having a diameter smaller than a minimum diameter past at least one portion of one of the fractionation sections.
