| 摘要 |
The present invention relates to a method of dividing a suspension, especially a fiber suspension into an accept fraction and a fraction containing impurity particles in a centrifugal cleaning plant having at least two stages, in which method the suspension is fed into a preceding stage (300, 400) of a reverse-function centrifugal cleaning plant, wherefrom heavier fraction is taken out as accept fraction (330, 430) and lighter fraction is taken out as fraction containing impurity particles, i.e. reject (320, 420), and the lighter fraction containing impurity particles, i.e. the reject (320, 420) is fed into a latter stage (340, 440) of the cenrifugal cleaning plant. The feed consistency of at least one latter stage (340, 440) of the reverse centrifugal cleaning plant is increased.
