AbstractA conveyor for a centrifuge and a centrifuge with such a conveyor, the conveyor having a plurality of spaced-apart flight members spaced apart along its length, a plurality of support members extending between, and connected to the flight members, the support members spaced-apart around the flight members, the members and support members defining a plurality of open areas through which fluid to be treated by the centrifuge is flowable from within the conveyor out into the bowl. In one aspect, a fluid velocity decreasing chamber is provided between an exit tube end and impeller apparatus for radially accelerating the fluid with the conveyor. In certain aspects the open "caged" conveyor structures diffuses fluid flow from the conveyor so that a dispersed unfocused flow of fluid exits the conveyor into the bowl, and, in one particular aspect with feed from within the conveyor to space adjacent a beach area of the bowl.
