ABSTRACT:
A process is provided for refining a pollutant laden suspension of waste paper using refining apparatus including a housing adapted to induce a turbulent flow in the suspension so as to separate the suspension into various fractions. Turbulent flow is created by the action of a rotary blade which is contained within a primarily rotation-symmetrical closed housing. The turbulent flow has a lower-pressure center about its axis. Along its radial edge, a fraction laden with heavy impurities or pollutants is removed while along the axial end where the rotary blade is positioned, a fraction of material is removed by a screen which is positioned next to the blade. Along the other axial end across from the end of the housing having the rotary blade, another fraction laden with pollutants is removed from the center. Air is fed directly into the refining apparatus where it is admixed with the suspension in order to facilitate separation of the suspension with the various fractions.
