A centrifuge basket shell formed by winding fiber-reinforced resin tape in a helical pattern over a thin shell plate which contains a plurality of holes for the passage of liquid therethrough, perforations being formed in the helix pattern of the wound tape by means of respective hollow ferrules connected rigidly to a cylindrical part of the shell plate, so as to enable liquid which passes through said holes in the shell plate to pass also through the helices of wound tape without increasing the stresses induced therein by rotation.

A centrifuge basket for a centrifuge of the type used in industrial processes for the separation of solids and liquids, comprising: a thin, metal, non-load bearing, inner shell having a cylindrical portion and respective annular end flange portions which are formed integrally with said cylindrical portion; a plurality of apertures formed in said cylindrical portion of the shell to enable fluid flow through the shell over at least part of said cylindrical portion thereof; a plurality of ferrules which are rigidly mounted to said cylindrical shell portion so as to extend radially outwardly therefrom and which are in communication with respective ones of said apertures; a continuous single winding of flat, fibre-reinforced resin tape formed in a helical mutilayer pattern of adjacent winding passes over said cylindrical portion and both said annular end flange portions of said thin shell such that said tape is substantially unstressed when the basket is not in rotation, said ferrules extending between adjacent passes of said helical winding to enable liquid which passes into said apertures in the shell to pass also between said adjacent winding passes of said wound tape; respective corner reinforcement pieces disposed between said cylindrical portion of the shell and said annular end flange portions, said reinforcement pieces being positioned intermediate inner and outer layers of the multi-layer helically wound tape; a cylindrical filter mesh disposed within said cylindrical portion of said basket shell; and a plurality of dimple means projecting radially inwardly from said cylindrical portion of said shell and engaging said cylindrical filter mesh at respective discrete contact points to provide a space between the shell and the filter mesh for aiding the flow of liquid through the basket.
