Description

ABSTRACT:
A centrifuge bowl of the type having a shell including a peripheral wall and a cast inner liner attached to the inside surface of the peripheral wall is modified by the provision of a plurality of punched channel portions which extend inwardly into the bowl from peripheral wall to define a U-shaped channel with severed ends. During the casting process the casting plastics material extends into the recess behind each channel portion and thus when set forms an insert portion which anchors the liner to the channel portion and thus to the peripheral wall. Openings for the entry of fluidizing water are then drilled through the insert portion from the outside of the shell through one end of the channel portion and through the liner into the interior of the bowl.
