Abstract (en)
[origin: WO9511093A1] This publication discloses a disk screen and method of its operation, said screen and method being suited for the screening of all types of soil including sticky clay soil. The screen is comprised of a plurality of parallel rotatable shafts (3) having intermeshing screen disks (4) adapted on them. The outer perimeter of the disks (4) is provided with ripping teeth (5) suited to rip off material from the raw feed. The shafts (3) of the disk screen are rotated cyclically in opposite directions of rotation, whereby the soil mass to be screened stays on the screen deck and will be ripped from its underside by virtue of the repetitive reversals of direction of rotation into screenable soil.
