Patent abstract
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. The suspension is fed to a preceding stage, wherefrom a heavier fraction of the suspension is taken as accept fraction and a lighter fraction is taken as fraction containing impurity particles. The lighter fraction containing impurity particles is fed into a latter stage of the centrifugal cleaning plant. Before being fed to the latter stage, the feed consistency of the lighter fraction is increased.
