  • Method and arrangement
    Patent number: 9370779
    Abstract: A method and an arrangement for treating stock formed of recycled fiber. The method comprises treating the stock in screen means and a flotation cell means, and screening the stock into accept and reject. Reject from the screening is directed to a mechanical dispergator and a dispersed reject is formed of it.
    Type: Grant

  • Method for controlling screening by measuring flow amount consistency of the pulp
    Patent number: 7077930
    Abstract: The invention relates to a method of controlling quality of pulp. Pulp formed in mechanical defibering of wood is screened into at least two fractions, the accept that has passed the screening phase being forwarded for further use and the reject that did not pass the screening being removed from the screening phase. The invention comprises determining flow amount and consistency of the pulp supplied to the screening phase and, correspondingly, of the reject removed therefrom, and calculating a passage ratio of the reject and the supplied pulp by means of the flow amounts and consistency values verified through the measurement, and adjusting the screening phase according to said passage ratio.

  • Method for controlling quality of pulp
    Patent number: 6846381
    Abstract: A method for controlling the quality of pulp. Pulp produced by mechanical defibering of wood is screened to provide at least two fractions, of which the accept that has passed the screening phase is carried forward for use and the reject that has not passed the screening is removed from the screening phase. The consistency of the reject that is to be removed from the screening is measured and the consistency value thus obtained is used for controlling the defibrator to adjust the quality of the accept.
