The inventions 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 the plane of the measuring surface are measured and both the magnitude and the direction of the forces are measured simultaneously. The invention also relates to a device for performing said method.
L'invention concerne un procédé de mesure de forces de contrainte dans des raffineurs comportant des disques de raffinage qui définissent entre eux un espace de raffinage destiné au matériau de raffinage entre des barres (3) qui sont placées sur les disques de raffinage. La mesure est effectuée sur une surface de mesure (2) qui constitue une partie du disque de raffinage. Cette surface de mesure 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 dans le plan de la surface de mesure et simultanément l'importance et la direction des forces. L'invention concerne enfin un dispositif permettant de mettre en oeuvre ce procédé.
