Description

Verfahren zur Zerkleinerung von Stoffen mittels in einem hohlringförmigen Mahlgehäuse umlaufender Kugeln. Die Erfindung betrifft eine magnetische Kugelmühle zum Zerkleinern aller Arten von Stoffen. Bekannte Ausführungen solcher -!Magnetmühlen haben den -Nachteil, daß zur Erzeugung der Mahlwirkung außer der Aufwendung elektrischer Energie in Form von Magnetfeldern auch noch mechanische Energie zur schnellen Umdrehung des Mahlgehäuses erforderlich ist.Process for the comminution of substances by means of a hollow ring-shaped Grinder housing rotating balls. The invention relates to a magnetic ball mill for shredding all kinds of materials. Well-known versions of such -! Magnetic mills have the disadvantage that to generate the grinding action apart from the use of electrical Energy in the form of magnetic fields as well as mechanical energy for rapid rotation of the grinder housing is required.

Die Erfindung vermeidet die Anwendung mechanischer Energie vollständig und erzielt das Umlaufen der Kugeln in dem feststehenden Malrlgehiiuse und damit die Mahlwirkung lediglich durch Anwendung des Einflusses von Magnetfeldern auf die Kugeln. Sie besteht darin, daß das Mahlgut in einem hohlringförmigen unmagnetischen Mahlgehäuse der Wirkung von magnetischen Eisenkugeln ausgesetzt wird, deren umlaufende Bewegung durch magnetische Drehfelder erreicht wird, wobei die magnetischen Drehfelder entweder solche nach Art der bei Drehstrommotoren verwendeten oder solche sein können, die durch um (-las Mahlgehäuse angeordnete Solenoide vermittels Gleichstroms, Wechselstroms oder Drehstroms erzeugt werden.The invention completely avoids the use of mechanical energy and achieved the rotation of the balls in the fixed Malrlgehiiuse and thus the grinding effect only by applying the influence of magnetic fields on the Bullets. It consists in the fact that the grist is in a hollow ring-shaped non-magnetic Grinder housing is exposed to the action of magnetic iron balls, their revolving Movement is achieved by rotating magnetic fields, the rotating magnetic fields either of the type used in three-phase motors or they can be, the solenoids arranged around (-las grinding housing by means of direct current, alternating current or three-phase current can be generated.

Zur Ausführung kann demnach beispielsweise ein aus unmagnetischem Stoffe, z. B. Granit oder Manganstahl, hergestelltes '#\Iahlgehäuse verwendet werden, in welchem die magnetischen Eisenkugeln laufen und welches ringsum von Solenoiden umgeben ist, in denen man einen oder mehrere Stromkreise in aufeinanderfolgenden Teilen der Solenoide schließen und öffnen kann, wodurch im Innern des Mahlgehäuses ein wanderndes magnetische Feld entsteht und die magnetischen Kugeln zum Umlaufen gezwungen werden. Man kann aber auch z. B. den Stator eines Drehstrommotors in wagerechter Lage mit einem hohlringförmigen Mahlgehäuse an Stelle des Ankers anwenden und die magnetischen Kugeln im Innern des so angeordneten Mahlgehäuses durch Anschluß des Stators an eine Drehstromleitung zum Umlaufen bringen.Accordingly, for example, a non-magnetic one can be used for execution Substances, e.g. B. granite or manganese steel, manufactured '# \ Iahlgehäuses can be used, in which the magnetic iron balls run and which around solenoids is surrounded, in which one or more circuits in successive Parts of the solenoids can close and open, creating inside the grinder housing a wandering magnetic field is created and the magnetic balls rotate are forced. But you can also z. B. the stator of a three-phase motor in horizontal position Apply location with a hollow ring-shaped grinding housing in place of the anchor and the magnetic balls inside the so arranged grinding housing by connecting the Make the stator rotate on a three-phase line.
