Abstract:
1. A method for preventing wear of a centrifugal separator screen, the method comprising the steps of: outfitting a separator screen with a series of dam segments, the dam segments being outfitted upon a circular outlet portion of the separator screen; rotating the separator screen about an axis of rotation so as to create a centrifugal separator screen; directing a first set of material through an inlet portion of the centrifugal separator screen; directing the first set of material into the dam segments along the centrifugal separator screen; damming the first set of material upon the centrifugal separator screen via the dam segments; spreading the first set of material upon the centrifugal separator screen via said damming action; directing a second set of material through the inlet portion of the centrifugal separator screen; and layering the second set of material upon the first set of material, the first set of material thereby providing a screen-protecting layer for preventing wear of the centrifugal separator screen.
