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.

Method and device for fragmenting and/or weakening pourable material by means of high-voltage discharges

A method of fragmenting and/or weakening of material is provided that utilizes high voltage discharges. The material is together with a process liquid introduced into a process area, in which two electrodes face each other at a distance, and is arranged therein in such a manner that the area between the two electrodes is filled with the material and process liquid. Between the two electrodes high voltage discharges are generated for fragmenting or weakening of the material. During the fragmenting or weakening, respectively, of the material, process liquid is discharged from the process area and process liquid is fed into the process area. The process liquid which is fed has a lower electrical conductivity than the process liquid which is discharged.
