Diese Schichte würde sich durch das stetig nachgefüllte Material stets vermehren, wenn sie nicht durch den zur Trommelachse geneigt liegenden Abstreicher n abgestrichen und unter den zweiten Mahlkörper k geschleudert würde. Dasselbe wiederholt sich von einem Mahlkörper zum anderen, von links nach rechts bis zum letzten.
Jeder Mahlkörper bearbeitet somit ein Mahlgut von verschiedener Feinheit. Der erste Mahlkörper, der beim Eintrittscanal des Materiales liegt, bearbeitet das ganz grobe Material, der zweite das durch den ersten vorgearbeitete Material und so fort.
In der beschriebenen Ausführungsform ist die Abfuhr des Mahlgutes aus dem Apparate mittelst eines Luftstromes erfolgend gedacht.
Eine beliebige Gebläsevorrichtung sendet einen Luftstrom durch den Zapfen b in die
EMI2.1
sprechend angeordneten Kammer in Verbindung steht, wo sich das Mahlgut absetzt.
Durch entsprechende Wahl der Intensität dos Luftstromes kann mit ein und demselben Apparat mehr oder weniger fein gemahlen werden.
Die Gcb ! äsevorrichtung kann derart eingerichtet sein, dass die Luft aus der Abscheidekammer dos Mahlgutes angesogen wird, so dass ein Cyclus entsteht. Die Lager d

This layer would always increase due to the constantly refilled material if it were not scraped off by the scraper n, which is inclined to the drum axis, and hurled under the second grinding body k. The same thing is repeated from one grinding medium to another, from left to right to the last.
Each grinding body thus processes a grist of different fineness. The first grinding body, which is located at the entry channel of the material, processes the very coarse material, the second the material prepared by the first and so on.
In the embodiment described, the removal of the ground material from the apparatus is intended to take place by means of an air stream.
Any blower device sends a flow of air through the pin b into the
EMI2.1
speaking arranged chamber is in connection, where the grist is deposited.
By choosing the intensity of the air flow, one and the same apparatus can be used to grind more or less finely.
The Gcb! The milling device can be set up in such a way that the air is sucked in from the separation chamber for the grist, so that a cycle is created. The camp d
