Abstract
An apparatus for separating out the contaminants in a pulp slurry in which the housing of the separator is divided by a perforated screen into an inlet and an outlet section. The inlet section of the separator has a rotating blade mixing means to propel the liquid mixture in the pulp slurry away from the screen and toward the housing wall. The outlet section of the separator has a rotating blade cleaning means which is adjacent the downstream side of the screen for removing contaminants from the upstream side of the screen and moving the removed contaminants into the inlet chamber for further mixing and removal therefrom.
