ABSTRACT:
A vertical or horizontal centrifugal separator comprises a drive mechanism including a drive shaft. A flight assembly is attached to the drive shaft and is rotatably driven by it as is a screen assembly which includes a rotor that also is attached to the drive mechanism. The flight assembly generally has a frusto-conical central body with a plurality of spaced apart individual blades or flights aligned longitudinally on the exterior of the central body. The rotor is driven at a separate speed that the flight assembly. A perforated screen assembly is carried by the rotor and is positioned outwardly of the flight assembly. An inlet assembly is positioned above these other elements where material to be separated is fed into the separator through the inlet assembly. An improvement comprises a novel tip formed on each of the individual flights. The novel tips is disposed to cause the solid material to collect on the tips and decelerated the propulsion of the material and cause the material to be propelled from the flights over a greater surface area of the screen thereby decreasing wear of the screen.
