  • Method and apparatus for measuring contaminating impurities in pulp slurry
    Patent number: 5512137
    Abstract: A method and apparatus for detecting impurities in raw pulp slurry at high precision using samples on-line. The pulp slurry is passed through a flat mesh wire to accumulate pulp fiber on the wire surface and prepare a wet mat, after which the surface of the wet mat is detected by a CCD camera in a catoptric system while pressed against a flat transparent plate, and the image is processed to measure the area of impurities per unit area of the wet mat.
