Abstract

Der Drucksortierer dient zur Entfernung von Störstoffen aus einer Papierfasersuspension (S) und weist ein Gehäuse (6) mit mindestens zwei Sieben (1, 2) auf. Die Siebe (1, 2) sind so angeordnet, dass sie nacheinander von der durch den Einlaufstutzen (3) in das Gehäuse eingeführten Papierfasersuspension (S) durchströmbar sind. In vorteilhaften Ausführungsformen ist der Drucksortierer mit feinen Schlitzen ausgestattet, wobei die Größe dieser Schlitze bei beiden Sieben (1, 2) etwa gleich ist. Der Drucksortierer eignet sich besonders zur Ausscheidung von feinen Störstoffen.
