Description

Es ist bekannt geworden, Stoffe dadurch zu zerkleinern, daß man sie gegen eine Prallwand o. dgl. schleudert.It has become known that substances can be crushed by beating them against a baffle or the like.

Vorliegende Erfindung stellt eine Verbesserung dieses Verfahrens dar. Sie besteht darin, daß man die starke Durcheinanderwirbelung durch eine Anzahl von außen in den Mühlenraum geleiteter Preßluft-, Preßgas- oder Preßflüssigkeitsströme bewirkt, die mehr oder weniger gegeneinander gerichtet sind und gleichzeitig gegen die Mitte einer umlaufenden Schüssel o. dgl. arbeiten.The present invention is an improvement on this method. It consists in that the strong turbulence through a number from the outside in the mill room guided compressed air, compressed gas or compressed fluid flows causes the more or less are directed against each other and at the same time against the center of a rotating bowl o. The like. Work.

Nach der vorliegenden Erfindung kann der Mahlvorgang selbst mit Unterbrechungen erfolgen, d. h. der Mahlraum wird mit Mahlgut gefüllt und dann verschlossen; die Vorrichtung arbeitet dann so lange, bis die genügende Feinheit erzielt ist. Er kann aber auch fortlaufend erfolgen, indem ein dauernder Zu- und AblaufAccording to the present invention, the grinding process itself can be carried out with interruptions, d. H. the grinding chamber is filled with ground material and then closed; the device then works until the sufficient fineness is achieved. But it can also be continuous take place by a permanent inflow and outflow

ao von Mahlgut stattfindet.ao of grist takes place.

Zweckmäßig kann man auch die hineingeleiteten Preßluft-, Preßgas- oder Preßflüssigkeitsströme selbst benutzen, um das genügend Feine aus der Mühle herauszuführen. Dies geschieht am einfachsten dadurch, daß man oberhalb der Mühle einen sog. Raumsichter o. dgl. anordnet, in welchem sich durch Querschnittserweiterung das noch nicht genügend Feine ausscheidet und wieder in den Mahlraum zurückfällt, während das genügend Feine mit der entweichenden Luft oder Flüssigkeit zweckmäßig am obersten Ende abgeführt wird.The compressed air, compressed gas or compressed liquid streams introduced can also be expediently used use it yourself to get what is sufficiently fine out of the mill. The easiest way to do this is by one Above the mill, a so-called room sifter or the like is arranged, in which the cross-section is enlarged what is not yet enough fine separates and falls back into the grinding chamber, while what is enough fine with it the escaping air or liquid is expediently discharged at the top end.

In der Zeichnung ist eine Möglichkeit der Erfindung schematisch dargestellt. Es bedeuten α den Mahlraum, O1, δ2 usw. die Leitungen für die gepreßte Luft, Gas oder die Flüssigkeit, c ist eine sich drehende Schüssel, die mittels Fliehkraft das auf ihr befindliche Mahlgut immer wieder gegen den Gas- oder Flüssigkeitsstrom schleudert.One possibility of the invention is shown schematically in the drawing. Α denotes the grinding chamber, O 1 , δ 2 and sw. The lines for the compressed air, gas or liquid, c is a rotating bowl which, by means of centrifugal force, repeatedly hurls the ground material on it against the flow of gas or liquid .

Das Mahlgut selbst kann nach der Erfindung entweder zusammen mit dem Gas- oder Flüssigkeitsstrom oder getrennt davon in die Mühle eingeführt werden. In beiden Fällen kann es von Vorteil sein, daß man brennbare Gas- oder Flüssigkeitsströme benutzt, die gleichzeitig zum Trocknen, Rösten, Sintern oder Schmelzen des Mahlgutes dienen.According to the invention, the ground material itself can either be used together with the gas or liquid flow or introduced into the mill separately. In both cases it can it may be advantageous to use flammable gas or liquid streams that simultaneously serve for drying, roasting, sintering or melting the grist.
