The invention relates to a method for the fragmentation and/or weakening of a piece of material (1) by means of high-voltage discharges. According to the method, the piece of material (1), immersed in a process fluid (5), is guided past a matrix (2) formed by a number of high-voltage electrodes (3) which are supplied with high-voltage pulses, such that high-voltage disruptive discharges occur through the piece of material whilst same is guided past the matrix (2). The high-voltage electrodes (3) can be moved independently of one another along movement axes (X) running substantially perpendicular to the passing direction (S, S2) of the work piece (1), and are moved, whilst the piece of material (1) is guided past and whilst the high-voltage disruptive discharges are generated, in such a way that each follows the contour of the piece of material (1) at a determined distance and are thereby immersed in the process fluid (5). With the method according to the invention, large pieces of material (1) of different shapes can be fragmented and/or weakened in a simple manner and without costly pre-crushing. |
