Patent ID: 7677486

Claim:
Assembly of an electrodynamic fractionating unit for the fragmenting, grinding, or suspending of a brittle material to be processed, said unit comprising: a chargeable electrical energy store with two electrodes connected to its output, wherein one of these electrodes is at reference potential while the other electrode can be admitted with a pulsed high voltage via an output switch on the energy store; a reaction vessel filled with a process fluid in which the material to be processed is submerged and the two exposed electrode ends are arranged at an adjustable distance opposite each other, thereby forming the reaction zone, wherein the electrode which can be admitted with high voltage is surrounded by an insulating casing right up to the exposed end region and wherein this insulating casing in the end region is also submerged in the process fluid; characterized in that, the energy store together with its output switch, the electrodes with feed line, and the reaction vessel are positioned in a completely enclosed volume surrounded by an electrically conductive wall, meaning the encapsulation, and that this volume enclosed by the encapsulation is at a minimum, the wall thickness of the encapsulation at least equals the penetration depth corresponding to the lowest component of the Fourier spectrum of the pulsed electromagnetic field and has at least the thickness required for the mechanical strength, that the electrode at reference potential is connected via the encapsulation wall to the ground potential side of the energy store, and that the electrode admitted with high voltage is connected via the shortest distance to the output switch on the energy store.
