Abstract
The separator screen arrangement of a centrifugal basket assembly reduces separator screen wear and eases structural replacement of worn parts. The centrifugal basket assembly comprises a screen-supporting basket; a separator screen, and a series of J-shaped dam segments. The separator screen is received and supported by the basket and comprises and inlet and a circular outlet end. The dam segments each comprise a dam portion, and a rim seat portion. The rim seat portions seat upon the rim, being attached thereto in a circular manner side-by-side such that the dam portions extend toward the inlet end. The dam portions dam material directed thereagainst from the inlet end so as to uniformly spread and layer material upon the separator screen before the material exits the basket assembly. The uniformly spread and layered material reduces wear of the separator screen. Material-drying and screen-protecting methodology is further supported by the basket assembly.
