KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Zweck der vorliegenden Erfindung ist die vollständige Separation des Eisens in Oolith-Erzen von dem erdigen Material desselben. Dieses ist sehr schwierig, weil das Eisen nicht magnetisch ist und sich in Form von kleinen Plättchen oder Täfelchen, umgeben von dem erdigen Stoff, befindet. Wenn diese erhitzt werden, um das Eisen magnetisch zu machen und dann Magnete für die Separation benutzen zu können, wird der erdige Stoff hart, backt zusammen und umgiebt die Täfelchen, so dafs sie durch den Magneten nicht völlig getrennt werden können.The purpose of the present invention is the complete separation of iron in oolite ores from the earthy material of the same. This is very difficult because the iron doesn't is magnetic and is in the form of small plates or tablets, surrounded by the earthy fabric. When these are heated to make the iron magnetic and then being able to use magnets for the separation, the earthy substance becomes hard, bakes together and surround the tablets so that they are not completely separated by the magnet can be.
Es ist daher nöthig, für die Separation mechanische Mittel zu benutzen, und bilden diese den Gegenstand der vorliegenden Erfindung.It is therefore necessary to use mechanical means for the separation, and form these the subject of the present invention.
Zuerst wird das Erz genügend zerkleinert oder pulverisirt, um die Plättchen von einander zu trennen, dann wird der erdige Stoff von den Täfelchen durch Abreibung der Krystalle auf einander und auf den Stücken des harten Materials gereinigt. Die Mischung von Eisen und erdigem Material bringt man nun in ein Sieb, wodurch die feinen Partikeln des erdigen Stoffes von den Eisentäfelchen getrennt werden. Die Krystalle oder Täfelchen von Oolith sind ungefähr von derselben Gröfse, und werden bei denen von einer Grube z. B. sämmtliche Täfelchen durch ein 60-Maschensieb hindurchgehen, während sie dagegen durch ein 70-Maschensieb zurückgehalten werden. Der umhüllende Stoff, der noch feiner ist, wird mit wenig Mühe und durch sehr einfache Mittel vollständig separirt.First the ore is crushed or pulverized enough to separate the platelets from one another Then the earthy substance is separated from the tablets by rubbing the crystals on one another and on the pieces cleaned of the hard material. The mixture of iron and earthy material brings one now in a sieve, whereby the fine particles of the earthy substance are separated from the iron tablets will. The crystals or tablets of oolite are about the same size, and are in those of a pit z. B. all tablets through a 60-mesh sieve while they are held back by a 70 mesh screen. The enveloping fabric, which is even finer, becomes very simple with little effort Means completely separated.
Der zur Ausführung dieser Erfindung dienende Apparat ist in beiliegender Zeichnung dargestellt. \Apparatus for carrying out this invention is shown in the accompanying drawing shown. \
AA sind Walzen, zwischen welchen das Material zerquetscht wird und von denen es in einen Trichter B fällt. Der drehbare, hohle Cylinder C besitzt auf einer Seite eine Oeffnung, welche durch einen Deckel a oder dergleichen geschlossen werden kann. Ein Theil des Materials -fällt von dem Trichter in diesen Cylinder; letzterer wird dann geschlossen und gedreht, bis durch die Reibung die erdigen Stoffe von den Eisenplättchen oder Tä'felchen getrennt sind. Den Cylinder dreht man schliefslich so weit, bis der Theil α sich über dem Trichter D befindet, und öffnet a, wodurch das Material, mit Ausnahme der grofsen Stücke, in den Trichter fällt, von wo es allmälig in das sich langsam drehende und schwach geneigte Cylindersieb E gelangt; dieses besitzt offene Enden, und wird das Material beim langsamen Niedergehen gesiebt und getrennt, wie bereits beschrieben. Die Eisentäfelchen fallen schliefslich von dem unteren. Ende des Cylinders herunter, während die feineren Theile des erdigen Stoffes auf die andere Seite der Scheidewand F fallen. AA are rollers between which the material is crushed and from which it falls into a hopper B. The rotatable, hollow cylinder C has an opening on one side which can be closed by a cover a or the like. Part of the material falls from the funnel into this cylinder; The latter is then closed and turned until the earthy substances are separated from the iron flakes or tablets by the friction. Finally turn the cylinder until the part α is above the funnel D , and open a, whereby the material, with the exception of the large pieces, falls into the funnel, from where it gradually falls into the slowly rotating and slightly inclined one Cylinder sieve E arrives; this has open ends and the material is sieved and separated as it slowly descends, as already described. The iron tablets finally fall from the lower one. End of the cylinder, while the finer parts of the earthy matter fall to the other side of the partition F.
