SYSTEM AND METHOD FOR AN ELECTRODYNAMIC FRAGMENTATION

The invention relates to a fragmentation system (1) for an electrodynamic fragmentation of material (5), comprising a feed (3) and an outlet (4) for transporting material along a transport path (8) in a transport direction (9), comprising at least one high-voltage pulse source (11), wherein each of the high-voltage pulse sources (11) has at least one first electrode (10a) and at least one second electrode (10b) for generating a high-voltage discharge (19) in a discharge chamber, and the transport path (8) has a fractionation section (18), said fractionation section (18) running through the discharge chamber. The fragmentation system also comprises a selection means for a selective discharge of the material (5) on the transport path in order to extract material (5) and/or fragments of the material with a diameter which is smaller than a minimum diameter at at least one part of one of the fractionation sections (18). In a method for an electrodynamic fragmentation of material (5), material (5) is transported from an inlet (3) to an outlet (4) along a transport path (9). The transport path (8) has a fractionation section (18), at least one high-voltage pulse source (11) has at least one first electrode (10a) and at least one second electrode (10b), and the high-voltage pulse source (11) generate a high-voltage discharge in a discharge chamber, said discharge chamber being arranged between the first electrode (10a) and the second electrode (10b). Material (5) and/or fragments of the material with a diameter which is smaller than a minimum diameter is extracted at at least one part of one of the fractionation sections (18). L'invention concerne une installation de fragmentation (1) servant à la fragmentation électrodynamique d'un matériau (5) et comportant une entrée (3) et une sortie (4) pour le transport du matériau sur un trajet de transport (8) dans une direction de transport (9), et au moins une source (11) d'impulsions haute tension, chacune des sources (11) d'impulsions haute tension comprenant au moins une première électrode (10a) et au moins une seconde électrode (10b) produisant une décharge haute tension (19) dans un espace de décharge. Le trajet de transport (8) présente une section de fractionnement (18), la section de fractionnement (18) traverse l'espace de décharge, et l'installation comporte un moyen de sélection servant à l'enlèvement sélectif du matériau (5) sur le trajet de transport pour faire passer le matériau (5) et/ou des fragments du m
