ABSTRACT:
A method of pulping baled waste material includes breaking up the bale and applying the broken bale to a fluffer or shredder to form a fluffed waste paper product containing heavy and light contaminants. This product is applied to an air separator from which heavier non-paper contaminant fraction is removed, and the remaining product is applied to the inlet of a vortex separator which removes a light reject fraction. A second accepts fraction is then water soaked and applied to the inlet of a series of drum-type pulpers. The invention further includes a drum-type pulper in which an axial shaft has radially-extending arms or buckets which dip into a pool of stock from waste paper in which the buckets sweep the interior of the drum, lift a quantity of the mixture from the pool, and allow the same to drop back into the pool. Vanes on the buckets cause the mixture to move axially in the drum from an inlet to an outlet.
