Patent ID: 8002209

Claim:
A fragmentation system for a more effective grinding of mineral and/or brittle materials, said system comprising: a reaction vessel provided with processing fluid and fragmentation product; a pair of electrodes adapted to be coupled to an energy store, wherein two respective ends of the pair of electrodes are arranged at a distance to each other inside the reaction vessel, wherein one of the pair of electrodes comprises a high-voltage electrode; wherein one of the two electrodes is connected to reference potential and the high-voltage electrode can be admitted by an output switch with pulsed high-voltage from the energy store to grind the fragmentation product positioned between the pair of electrodes in a reaction zone; a solid/fluid separation device coupled to the reaction vessel; a suspension device to keep the fragmentation product continually suspended in the processing fluid, is mounted on or in the reaction vessel; a transfer device is mounted on or in the reaction vessel to transfer processing fluid and a first share of the fragmentation product that is below or equal to a target particle size out of the reaction vessel to the solid/fluid separation device, and wherein a second share of the fragmentation product with particles sizes exceeding the target particle size is returned to the reaction zone; and at least one return-flow line coupled to the solid/fluid separation device and the reaction vessel to empty the processing fluid from the solid/fluid separation device into the reaction vessel.
