ABSTRACT:
A scroll-conveyor centrifuge for separating a suspension into at least a liquid phase and solid material which is deposited through centrifugal force on the interior surface of the centrifuge bowl and which is conveyed along that surface to the solid material discharge opening located at an axial end portion of the bowl through rotation of the centrifuge helix at a differential rate with respect to the bowl. Abrasion of the interior bowl surface and operating power requirements due to movement of the solid material in the direction of the bowl circumference are both reduced by the simple expedient of applying to the interior bowl surface a texturing through the spray application of a thin adhering layer having a rough surface facing the helix.
