Die vorliegende Erfindung betrifft eine besonders für schvvachmagnetisches Aufbereitungsgut geeignete Ausführungsform des Verfahrens und der Vorrichtung des Patents 115808.The present invention relates to an embodiment of the method which is particularly suitable for weak magnetic material to be processed and the device of patent 115808.

Statt das Gut auf der ansteigenden Seite des Magnetsystems aufzugeben, so dafs es auf dem letzteren aufwärts befördert werden mufs, wird dasselbe entweder auf dem Gipfel oder an der absteigenden (fallenden) Seite des Systems aufgegeben, wandert also mit der Wanderrichtung des magnetischen Feldes bezw. der Magnetcurve an dem Magnetsystem abwärts. Hierdurch wird erzielt, dafs beim Aufgabeorte das Gut leichter dem Einflufs der magnetischen Kraft unterliegt, indem hier die durch das Eigengewicht bezw. die Schwerkraft bedingte Richtung, in welcher sich das Gut naturgemäfs zu bewegen sucht, mit der Richtung, in welcher die magnetische Kraft es mitzunehmen sucht, übereinstimmt, während bei der Aufgabeweise des Haupt-Patents die beiden Kräfte bezw. Bewegungsrichtungen einander entgegengesetzt sind und wirken. Hat man es nun, wie beim Haupt-Patent angenommen, lediglich mit stark oder gut magnetischem bezw. der Einwirkung des Magnetismus leicht unterliegendem Gut zu thun, so schadet die der Fallrichtung entgegengesetzte Bewegungsrichtung der Magnetcurve nicht, befördert vielmehr ein schnelles und leichtes Abfallen der unmagnetischen Beimengungen. Will man dagegen schwach magnetisches Gut von unmagnetischem sondern, so ist aus oben angeführtem Grunde die Uebereinstimmung beider Bewegungsrichtungen vorzuziehen. Es braucht dabei dann die Wanderung des Magnetfeldes bezw. der Magnetcurve nicht das Gewicht des Materials aufwärts zu befördern, also dieses auch zu tragen, sondern die magnetischen Theilchen bewegen sich im Wesentlichen unter der Einwirkung der Schwerkraft, während dabei die Bewegung der Magnetcurve höchstens etwas fördernd und festhaltend wirkt, im Wesentlichen aber allein zur Erzeugung der kleinen localen Hüpf-, Spring- und Schüttelbewegungen der einzelnen Materialtheilchen beim abwechselnden Umpolen und Entmagnetisiren dient.Instead of giving up the good on the rising side of the magnet system, so that it is on the the latter must be promoted upwards, the same thing is done either on the summit or on the descending one Abandoned (falling) side of the system, so migrates with the direction of travel of the magnetic field or. the magnetic curve down the magnet system. In this way it is achieved that the goods are more easily exposed to the influence of the magnetic ones at the place of application Force is subject by the BEZW by its own weight. caused by gravity Direction in which the good naturally seeks to move, with the direction in which the magnetic force seeks to take it away, while in the Task of the main patent the two forces BEZW. Directions of movement to each other are opposite and work. If it has now been assumed, as in the case of the main patent, only with strong or good magnetic bezw. the action of magnetism easily To deal with the underlying good, the direction of movement opposite to the direction of fall is harmful the magnetic curve, rather it promotes a quick and easy dropping of the non-magnetic additions. On the other hand, if one wants weakly magnetic goods from non-magnetic ones Instead, for the reason given above, it is preferable that both directions of movement coincide. It takes then the migration of the magnetic field BEZW. the magnetic curve is not the weight of the To convey material upwards, that is to say to carry it as well, but the magnetic particles move essentially under the action of gravity, while doing the Movement of the magnetic curve at most has a somewhat promoting and retaining effect, essentially but only to produce the small local hopping, jumping and shaking movements of the individual particles of material in alternating polarity reversal and demagnetization.

Diesem abgeänderten Verfahren entspricht auch die Abänderung der Vorrichtung. Die Zeichnung zeigt diese in ihrer abgeänderten Gestalt.The modification of the device also corresponds to this modified method. the Drawing shows this in its modified form.

Dabei ist die Vorrichtung zur Aufgabe des Gutes, z. B. ein Trichter T, auf dem Gipfel oder wenigstens oben an der absteigenden Seite des rad- oder bogenförmigen Systems der Magnete M₁ M₂ u. s. w. angeordnet. DieThe device is for the task of the goods, for. B. a funnel T, on the summit or at least above on the descending side of the wheel or arcuate system of magnets M ₁ M _2, etc. arranged. the

Claims

Rotation of the entire wheel-shaped system consisting of the magnets, the lead wires and the collector C against the stationary brushes, or of the latter against the then standing still system consisting of the collector, lead wires and magnets arranged in an arc, takes place in the opposite sense, as in the apparatus of the main patent, and also the continuous polarity reversal of the magnets takes place in reverse order. The natural consequence of this arrangement is that the magnetic field and the magnetic curve along with the good migrate downwards, the separation of the latter taking place, in that the non-magnetic particles only go with it as far as the sloping point of the system, or else the magnetic particles run ahead of the magnetic ones and fall off here, for example into a container Aj, while the magnetic particles continue to migrate along the magnet system to its lowest point and are made to fall off here, e.g. B. in a container A 2. The fall at this point can be caused in various ways, e.g. B., as shown, by a scraper, or by demagnetizing the lowest magnet, etc. Since the weakly magnetic material to be processed for separation is usually crushed as evenly as possible before the task, so that the individual parts can be better and more quickly influenced by the magnetic force and their individual weight will decrease. A measuring or regulating device is expediently arranged on the feeding device in order to direct the material to the magnet system in regular quantities, that is to say in an even current as far as possible. An impeller attached in front of the outlet of the feed hopper can serve as such a device, as has already been used for the same purpose for magnetic ore separators. Godfather nt-A ν Proverbs:

1. An embodiment particularly suitable for weakly magnetic material to be processed by claim ι of the patent 11 5808 protected method for magnetic separation, characterized in that the material to be processed, instead of increasing Abandoned side of the magnet system to be carried up on the same, on the summit or the descending Side of the system is abandoned and migrates down the same.

2. To carry out the method according to claim 1, a device characterized by the arrangement of the feed device T on the summit of the wheel-shaped or arcuate system of magnets (M ₁ M _2, etc.), or at the top of its descending side, the rotation of the whole wheel-shaped system consisting of magnets, line wires and collector against the stationary brushes, or the latter against the stationary system consisting of collector, line wires and magnets arranged in an arc and thus the continuous polarity reversal of the magnets in the opposite sense, as in patent 1 1 5808 takes place, so that the magnetic field and the magnetic curve, and thus at the same time the material influenced by magnetism, migrates downwards and falls at the lowest point of the magnet system in container (A ₂ ) , after the non-magnetic parts of the material have already reached the sloping point of the system in Container (A ₁ ) have crashed.
