ABSTRACT:
A screening apparatus comprises a pair of stationary concentric screens with a plurality of foils rotating therebetween and adjacent thereto, the individual foils being radially aligned. The screening apparatus comprises a tangentially disposed slurry inlet and a diametrically and tangentially disposed heavy rejects outlet at the end of a heavy rejects trap. The light reject/accepts slurry flows into the screening zone and, after separation, is discharged at an end of the screening apparatus by way of respective light rejects and accepts outlets. The accept outlet is located axially with respect to the screen cylinders and rotating foils so the pressure pulses are virtually eliminated in the screening process. The apparatus may be constructed for vertical or horizontal rotation of the foils.
