Abstract

An agricultural combine having a transverse threshing cylinder and concave and an axial separator. The axial separator is provided with two side-by-side axial separator units, each unit having a rotor and a casing for housing the rotor. The casings are non-concentric housing having a semi-circular top, a semi-circular bottom and straight side walls joining the top and bottom. The rotor is provided with fixed teeth that extend radially outward from the rotor. The rotor is located at the bottom of the casing so the teeth can engage and penetrate the crop material at the bottom of the casing. The rotor throws the crop material upwardly against the top of the casing which is provided with downwardly projecting spiral vanes for directing the crop rearwardly. The rotor is rotated so that the tip speed of the teeth is greater than or equal to 11.8 m/sec and less than or equal to 20.9 m/sec.
