ABSTRACT:
The invention provides for a seal assembly for a grain separator. The grain separator may include a housing, a rotatable grain separation cylinder within the housing, the cylinder having an end surface, a grain inlet having an inlet spout extending through the end surface for conveying grain into the cylinder in a feed zone, an auxiliary end piece or seal cone functionally connected to the end surface of the cylinder. The auxiliary end piece may have an annular external surface spaced laterally from the feed zone, and a seal interfacing with the annular external surface, thereby defining a seal zone spaced laterally from the feed zone. Such grain separators have increased capacity compared to separators with traditional seal assemblies.
