| 摘要 |
Methods of measuring stress forces in refiners are disclosed in which the refiners include refining disks with a refining surface and refining bars extending across the refining surface, as well as a measuring surface comprising a portion of the refining surface, the measuring surface being movably mounted on the surface of at least one of the refining disks and a pair of rigidly mounted force sensors for producing oppositely directed deflections when the measuring surface is influenced by stress forces, the method comprising resiliently mounting the measuring surface in a direction parallel to the surface of the refining disk and calculating the stress force based on the difference between the deflections measured by the respective pairs of the force sensors. Apparatus measuring stress forces in such refiners are also disclosed.
