Abstract
A method for fragmenting and/or weakening of pourable material by means of high-voltage discharges is disclosed. Thereby, a material flow of the pourable material is, immersed in a process liquid, guided past a high-voltage electrode assembly with one or more high-voltage electrodes, while high-voltage punctures through the material are produced by means of charging of the high-voltage electrodes with high-voltage pulses. The zone of the material flow in which the high-voltage punctures through the material are produced is delimited laterally by substantially unmoved zones of the same material as viewed in a guiding-past direction. With the disclosed method, it becomes possible to fragment and/or weaken pourable material in a continuous process by means of high-voltage punctures in a low-wear and low-contamination manner.
