The invention relates to an electrode arrangement for an electrodynamic fragmentation plant having a passage opening (1) for fragmentation material (3) and having several electrode pairs (4a, 5a; 4a, 5b; 4b, 5c; 4b, 5d; 4c, 5e; 4c, 5f; 4d, 5g; 4d, 5h) by means of which, by charging the electrodes (4a-4d, 5a-5h) thereof with high-voltage pulses, in each case high-voltage discharges can be generated within the passage opening (1), for fragmentation of the fragmentation material (3). The passage opening (1) is formed in such a way and the electrodes (4a-4d, 5a-5h) of the electrode pairs are arranged therein in such a way that for each electrode pair (4a, 5a; 4a, 5b; 4b, 5c; 4b, 5d; 4c, 5e; 4c, 5f; 4d, 5g; 4d, 5h) in the area of a shortest connecting line (L) between the electrodes of the respective electrode pair, a ball (K) can pass through the passage opening (1), the diameter of which is bigger than the length of this respective shortest connecting line (L). With such an electrode arrangement it is possible to carry out an electrodynamic fragmentation of fragmenatation material in an economical manner with comparatively small high-voltage pulses. This also results in the possibility of expanding the realizable target value range of existing plants considerably in the direction of larger target values by retrofitting such plants with the electrode arrangement according to the invention. |
