The invention relates to a method for measuring stress forces in refiners having refining discs that between them define a refining gap for refining material between bars (3) arranged on the refining discs. The measuring is performed over a measuring surface (2) that constitutes a part of a refining disc, said measuring surface comprising at least parts of more than one bar (3) and being resiliently arranged in the surface of the refining disc. Furthermore, forces in a plane at right angles to the measuring surface are measured. The invention also relates to a device for performing said method.
L'invention concerne un procédé de mesure des forces de contrainte dans les raffineurs comportant des disques de raffinage qui définissent entre eux un espace de raffinage destiné au raffinage du matériau de raffinage entre des barres (3) qui sont placées sur les disques de raffinage. La mesure est réalisée sur une surface de mesure (2) qui constitue une partie d'un disque de raffinage. Cette surface de raffinage comprend au moins des parties de plus d'une barre (3) et est réalisée résiliente dans la surface du disque de raffinage. On mesure également des forces se produisant dans un plan à angle droit de la surface de mesure. L'invention concerne enfin un dispositif permettant de réaliser ce procédé.
