Abstract
A disc for use in a disc screen is disclosed. The disc has a longitudinal axis and includes a hub extending a length along the longitudinal axis. The longitudinal axis is coaxial with the center of the hub and the hub further includes a hub surface, a major axis defined by a first cross section taken perpendicular to the longitudinal axis and through the center of the hub at and a minor axis defined by a second cross section taken perpendicular to the longitudinal axis and through the center of the hub. The first cross section is longer than the second cross section, and the first cross section is substantially orthogonal to the second cross section. A helical ridge structure extends away from hub surface and twists at least 360 degrees about the longitudinal axis for the length.
