EP 86 902 922.3 PatentansprücheEP 86 902 922.3 Patent claims 1. Verfahren zum Steuern der Herstellung von mechanischer Pulpe in einem Mahlprozess, wobei zellulosehaltiges klumpiges Material während des Durchgangs durch den Zwischenraum zwischen zwei gegenüberliegenden Mahlscheiben, die sich relativ zueinander drehen, gemahlen wird, dadurch gekennzeichnet, daß die Vibrationen von mindestens einer Mahlscheibe mit1. A method for controlling the production of mechanical pulp in a milling process, whereby cellulosic lumpy material is milled during passage through the space between two opposing milling discs rotating relative to each other, characterized in that the vibrations of at least one milling disc are Hilfe eines Beschleunigungsmessers, der an der Scheibe JUsing an accelerometer mounted on the disc J angebracht ist, gemessen und in Vibrationsenergie umgewandelt werden, welche zusammen mit einer oder mehreren Prozessvariablen für die Steuerung des Mahlprozesses und der Eigenschaften der hergestellten Pulpe verwendet werden.is mounted, measured and converted into vibration energy, which together with one or more process variables is used to control the grinding process and the properties of the pulp produced. 2. Verfahren nach Anspruch 1, wobei der Mahlvorgang in einem Einscheiben-Refiner durchgeführt wird, dadurch gekennzeichnet, daß die Vibrationen in einem Scheibensegment, das auf der stationären Scheibe im Refiner angeordnet ist, gemessen werden.2. Method according to claim 1, wherein the grinding process is carried out in a single-disk refiner, characterized in that the vibrations are measured in a disk segment arranged on the stationary disk in the refiner. 3. Verfahren nach den Ansprüchen 1 oder 2, dadurch gekennzeichnet, daß die Steuerung auf der Vibrationsenergie in Kombination mit der Produktion, Zwischenraumgröße und Materialkonzentration basiert.3. Method according to claims 1 or 2, characterized in that the control is based on the vibration energy in combination with the production, gap size and material concentration. 4. Verfahren nach einem der vorhergehenden Ansprüche,4. Method according to one of the preceding claims, &igr; dadurch gekennzeichnet, '&igr; characterized by ' daß die Vibrationsenergie auch zur Bestimmung des Zustandes der Mahlfläche der Scheibensegmente verwendet wird.that the vibration energy is also used to determine the condition of the grinding surface of the disc segments. 5. Verfahren nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet,5. Method according to one of the preceding claims, characterized in daß die Vibrationsenergie zur Auswertung und zum Vergleich zwischen verschiedenen Scheibensegementmodellen verwendet wird.that the vibration energy is used for evaluation and comparison between different disk segment models.
