Abstract

According to a method for fragmenting of pourable material by high-voltage discharges, a material flow of the material, immersed in a process liquid, is guided past an electrode assembly by a conveying device carrying the material flow. By charging the electrode assembly with high-voltage pulses, high-voltage punctures through the material of the material flow are produced. The electrodes of the electrode assembly are immersed in the process liquid from above, and those of these electrodes between which the high-voltage punctures are produced face each other with an electrode spacing transverse to the material flow direction.
