Description
Verfahren zur Herstellung von Aluminiumgriess. Aluminiumgriess wurde bisher durch Zer stäuben von geschmolzenem Aluminium her, gestellt. Die auf diese Weise erhaltenen Körper weisen eine glatte Oberfläche auf, die vielfach unerwünscht ist.
Anderseits ist es auch bereits bekannt, kleinstückiges Material auf Kugelmühlen zu runden und hierbei kugelartige Gebilde zu erzeugen. Hiezu ist es erforderlich, das Metall vorerst durch einen besonderen Arbeitsgang vor der Einführung in die Kugelmühle in eine blättchenförmige Beschaffenheit überzu führen.
Das Verfahren nach der Erfindung wird derart durchgeführt, dass das Aluminium in Form von Folien den Schlaghämmern einer Schlagmühle auf einer Rutsche zugeführt und durch die rotierenden Hämmer der Schlagmühle zerrissen wird, worauf die so erhaltenen Aluminiumflocken durch die rotie renden Hämmer zu Körnern geformt werden.
Process for the production of aluminum grit. Aluminum grit was previously made by dusting molten aluminum. The bodies obtained in this way have a smooth surface, which is often undesirable.
On the other hand, it is already known to round small pieces of material on ball mills and to produce ball-like structures. For this purpose, it is necessary first of all to convert the metal into a lamellar texture through a special operation before it is introduced into the ball mill.
The method according to the invention is carried out in such a way that the aluminum in the form of foils is fed to the hammers of a hammer mill on a slide and torn by the rotating hammers of the hammer mill, whereupon the aluminum flakes thus obtained are shaped into grains by the rotating hammers.
