An auger conveyor has a first auger flight (11) rotating about a first axis within a first tube (12) towards an end of the first tube, part of the first tube adjacent said end being angled away from the first axis to feed the material conveyed by the first flight at an angle to the first axis. The portion of the first auger flight adjacent the end is set to tend to throw the material being conveyed by the first flight radially/tangentially away for the fist axis into the angled part (16) of the first tube. The fist tube (12) may feed the conveyed material into a second tube (14) extending at an angle to the first tube, the material being conveyed along the second tube by a second auger flight (13) rotating about a second axis within the second tube. Alternatively, the angle part of the fist tube is flared radially outwardly (14a) to feed material, in the form of harvested tailings, into a rethreshing housing (21) of a combine harvester rethreshing device (20).
