The rotor of an axial flow rotary separator carries a series of circumferentially spaced threshing bars which move in a threshing relationship with a cylindrical threshing grate as the rotor rotates and are characterized in having upstream and downstream portions, respectively providing greater and lesser grate clearances, the greater clearance of the upstream portion facilitating the entry of material into the threshing section of the separator.
