wandert. Die Aufgabe erfolgt bei Al'Das unmagnetische Gut bleibt am Bande liegen und wird bei U ausgetragen.
Mit diesen Anordnungen kann man auch auf nassem Wege scheiden, wobei das magnetische Gut beispielsweise der Wasserströmung entgegengeführt wird, während das unmagnetische Gut mit der Wasserströmung abgeführt wird.
Man kann das Förderband (Fig. 4) aber auch weglassen und trotzdem nass scheiden, wobei sich die Anordnung gemäss Fig. 5 ergibt, die nur zur besseren Erläuterung des Verfahrens dient, ohne einen neuen Erfindungsgedanken zu enthalten. Auf das Wanderfeld ist hier ein Trog aufgesetzt. Das Scheidegut wird bei A nass aufgegeben, es fliesst durch Düsen D nahe am Wanderfeld aus. Der magnetische Anteil wandert (wie in Fig. 4) mit dem Wanderfeld in der Richtung des Pfeiles P1 und wird bei W mit Frischwasser nochmals abgespült und wandert sodann in der Richtung M1, M2, um bei Ms abzufallen.
Das unmagnetische Gut fliesst durch regelbare Rohre oder Schlitze RI a aus dem Trog heraus.
Besondere Wirkungen erzielt man auch durch Anpassung der Frequenz des Wechselstromes bzw. der Gleichstromstösse an die Korngrösse und an die magnetische Leitfähigkeit des magnetischen Gutes. Es eignen sich Frequenzen bis etwa von 10 bis 50 besonders für feine Körnungen und Perioden-

PATENT-ANSPRÜCHE :
1. Vorrichtung zur magnetischen Trennung loser Körpergemisehe durch elektromagnetische Wanderfelder, dadurch gekennzeichnet, dass ein zylindrisch geschlossenes Drehfeld mit eingebauten Leitspiralen für das magnetische Gut vorgesehen ist.

wanders. The task takes place at Al'The non-magnetic material remains on the belt and is carried out at U.
With these arrangements it is also possible to divide by wet means, the magnetic material, for example, being directed against the water flow, while the non-magnetic material is carried away with the water flow.
However, the conveyor belt (FIG. 4) can also be omitted and it is still parted wet, the result being the arrangement according to FIG. 5, which only serves to better explain the method, without containing a new inventive concept. A trough is placed on the moving field here. The material to be separated is fed in wet at A, it flows out through nozzles D close to the traveling field. The magnetic component migrates (as in FIG. 4) with the traveling field in the direction of arrow P1 and is rinsed off again with fresh water at W and then migrates in the direction of M1, M2 to drop at Ms.
The non-magnetic material flows out of the trough through adjustable pipes or slots RI a.
Special effects can also be achieved by adapting the frequency of the alternating current or direct current surges to the grain size and the magnetic conductivity of the magnetic material. Frequencies up to about 10 to 50 are particularly suitable for fine grains and period
