ABSTRACT:
A disc screen for classifying material by size. The disc screen comprises a frame, a plurality of shafts mounted on the frame parallel with one another, a first stage including discs mounted on the shafts in a substantially coplanar row, each of the discs having a perimeter shaped to maintain the space between discs substantially constant during rotation; and a second stage including discs mounted on the shafts in a substantially coplanar row, each of the discs having a perimeter shaped to maintain the space between discs substantially constant during rotation. The first stage discs are positioned to allow passage of only small fraction material and the second stage discs are positioned to allow passage of intermediate fraction material thereby classifying the material into a small fraction, an intermediate fraction and a large fraction.
