Method for operating a fragmentation system and system therefor

A fragmentation system including a reaction vessel with processing fluid and fragmentation product and a pair of electrodes. Two respective ends of the pair of electrodes are arranged at a distance to each other inside the reaction vessel and can be admitted with pulsed high-voltage to grind the fragmentation product positioned in a reaction zone. The system also including a solid/fluid separation device, a suspension device to keep the fragmentation product continually suspended in the processing fluid, and a transfer device to transfer processing fluid and a first share of the fragmentation product out of the reaction vessel to the solid/fluid separation device. A second share of the fragmentation product returns to the reaction zone. The system includes 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.
