Electrode arrangement for an electrodynamic fragmentation plant

摘要

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 fragmentation 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.

主权项

1. An electrode arrangement for an electrodynamic fragmentation plant, the electrode arrangement comprising:
a passage opening or passage channel for fragmentation material; at least one pair of electrodes, wherein charging the electrodes with high-voltage pulses generates high-voltage discharges within the passage opening or passage channel for fragmentation of fragmentation material; a connecting line extending through the passage opening or channel and between the pair of electrodes, the connecting line representing a shortest distance between the pair of electrodes in a direction extending transverse to a central axis of the passage opening or channel; and at least one passage for the fragmentation material defined by the passage opening or passage channel the at least one passage extending over an entire length of the passage opening or passage channel and having a diameter that is bigger than a length of the connecting line.
