Abstract

Das erfindungsgemäße Verfahren zur Zerkleinerung von Mahlgut verwendet eine Rohrmühle (1) mit wenigstens einer ersten und einer zweiten Mahlkammer (2,3) und einen Mittenaustrag (4) sowie einen Sichter (5), wobei
a. Mahlgut verwendet wird, das wenigstens eine erste und eine zweite Frischgutkomponente (6,7) aufweist, wobei die erste Frischgutkomponente (6) leichter mahlbar als die zweite ist und die zweite Frischgutkomponente (7) verschleißender als die erste ist,
b. die erste Frischgutkomponente (6) der ersten Mahlkammer (2) aufgegeben, dort unter Einwirkung von Mahlkugeln zerkleinert und über den Mittenaustrag (4) ausgetragen wird,
c. das aus der ersten Mahlkammer (2) ausgetragene Mahlgut dem Sichter (5) zugeführt wird,
d. die zweite Frischgutkomponente (7) zusammen mit Grobgut (10) des Sichters (5) der zweiten Mahlkammer (3) zugeführt, dort unter Einwirkung von Mahlkugeln zerkleinert und über den Mittenaustrag (4) ausgetragen wird,
e. das aus der zweiten Mahlkammer (3) ausgetragene Mahlgut dem Sichter (5) zugeführt wird und
f. das Feingut (9) des Sichters (5) als Fertiggut abgezogen wird.

The inventive method for comminuting regrind uses a tube mill (1) with at least a first and a second grinding chamber (2,3) and a center discharge (4) and a separator (5), wherein
a. Ground material is used, which has at least a first and a second Frischgutkomponente (6,7), wherein the first Frischgutkomponente (6) easier grindable than the second and the second Frischgutkomponente (7) is more wear than the first,
b. the first Frischgutkomponente (6) of the first grinding chamber (2) abandoned, there crushed under the action of grinding balls and on the center discharge (4) is discharged,
c. the millbase discharged from the first grinding chamber (2) is fed to the classifier (5),
d. the second Frischgutkomponente (7) together with coarse material (10) of the classifier (5) of the second grinding chamber (3), where it is crushed under the action of grinding balls and discharged through the Mittenaustrag (4),
e. the millbase discharged from the second grinding chamber (3) is fed to the classifier (5) and
f. the fines (9) of the classifier (5) is deducted as finished goods.
