Im dargestellten Ausführungsbeispiel wirkt der Druckzylinder 7 in einem Mittelbereich zwischen Mahlrolle 1 und Lager 6 auf den Kraftarm 5. Im Rahmen der Erfindung wäre es aber auch denkbar, dass die Positionen von Lager und Druckzylinder vertauscht sind.In the illustrated embodiment, the pressure cylinder 7 acts in a central region between the grinding roller 1 and bearing 6 on the power arm 5. In the context of the invention, it would also be conceivable that the positions of bearing and pressure cylinder are reversed.
