Abstract: A centrifuge of the type which has a central slurry feed pipe, a rotating bowl, and a concentric conveyor which includes a tubular shaft with a helix on the outside. The shaft has rectangular openings in the area of the slurry feed with rectangular orifice plates of hardened material fastened inside the shaft. The orifice plate is sealed to the shaft so that it forms a lip, retaining a pool of slurry within the shaft. The orifice plate is also smaller than the opening and overlaps the trailing edge of the opening.
