Abstract: An auger assembled from a plurality of auger segments each of which includes a central longitudinal hollow hub with a longitudinal extension at each end of the hub. A section of helical flighting winds about the hub extending from the extension at one end of the hub to the extension at the other end. The end portions of the helical flighting are beveled to provide an acute edge and a supplementary obtuse edge of the flighting at each end portion. The auger segments have end-for-end symmetry and a plurality of segments are assembled in an end-to-end relationship about a main drive shaft to comprise the auger. When assembled to form the auger, the beveled end portions of adjacent segments overlap in a matching relationship to create a substantially smooth continuous helical flighting surface over the length of the auger. Similarly, the longitudinal extensions of adjacent augers join to create a substantially continuous outer periphery of the assembled hubs.
