  • Monitoring and controlling of refining of fibrous pulp
    Patent number: 11788229
    Abstract: The refining of a fibrous pulp is monitored and controlled by capturing at least one image of a pulp sample, determining the amount of all fibers or non-fibrillated fibers in the at least one image, determining the amount of fibrillated fibers in the at least one image, determining the relation between fibrillated fibers and all fibers or non-fibrillated fibers in the pulp on the basis of the amount of fibrillated fibers and the amount of all fibers or non-fibrillated fibers in the at least one image, generating a control parameter on the basis of the determined relation between fibrillated fibers and all fibers or non-fibrillated fibers in the pulp, and controlling fiber refining by at least one pulp refining device on the basis of the control parameter.
