ABSTRACT:
An apparatus is disclosed for separating material by length into first and second fractions containing, respectively, material longer than a specified length and material shorter than a specified length. The apparatus includes a plurality of generally parallel shafts having disks attached thereto. The disks are spaced on the shafts a distance approximately equal to one-half the specified length. Shaft diameters and shaft spacings are selected to cause material in the first fraction to remain supported by the shafts and to flow along the shaft surfaces from one shaft to the next adjacent downstream shaft, while material in the second fraction tilts and falls downwardly between adjacent shafts.
