  • Variable geometry centrifugal basket
    Patent number: 10913015
    Abstract: A screen assembly including at least upper and lower portions each with screen elements having different orientations. The upper portion includes a first plurality of screen elements and the lower portion includes a second plurality of screen elements. The upper and lower portions are coupled together to form a truncated conical arrangement. At least one screen element of the first plurality of screen elements has a different angular orientation relative to a plane that is perpendicular to the central longitudinal axis than at least one screen element of the second plurality of screen elements has relative to the plane. In some such embodiments, the screen elements of the second plurality of screen elements are each oriented to be in a respective plane that is substantially perpendicular to the central longitudinal axis. The screen assembly may be configured to separate a liquid component and a solid component from a slurry.
