A method comprising rotating a rotor to expel, radially, a mixture of grain and material other than grain (MOG) from the rotor and past a rotor cage encircling the rotor; causing an air flow in a substantially arcuate channel defined by the rotor cage, a first cover assembly covering a substantial portion of the rotor cage, and a passive sieve, to entrain a first portion of the MOG; capturing a first portion of the grain with the first cover assembly and plural vanes located along the length and on the interior surface of the first cover assembly, the captured grain sliding by gravity along the vanes to the passive sieve, the captured grain comprising threshed and unthreshed portions; enabling the passage of the captured grain through the passive sieve and into a second channel within which a grain conveying assembly is disposed; conveying with the grain conveying assembly the passed, unthreshed portion rearwardly; and conveying with the grain conveying assembly the passed, threshed portion forwardly. |

1. A combine processing system, comprising:
a rotor; a rotor cage encircling the rotor, the rotor cage comprising opposing first and second side rails; a first cover assembly comprising first and second arcuate portions collectively surrounding a substantial portion of the rotor cage, the first arcuate portion removably affixed to the first side rail and the second arcuate portion removably affixed to the second side rail, the first and second arcuate portions each comprising a plurality of vanes, the plurality of vanes disposed on an interior surface along the length of each of the first and second arcuate portions, each of the plurality of vanes extending proximally between a top location and a bottom location of the respective arcuate portion; a passive sieve connected to the interior surface along the length of the first and second arcuate portions and proximal to the bottom locations; a second cover assembly disposed beneath the passive sieve and along the length of the passive sieve; and an auger assembly disposed between the second cover assembly and the passive sieve. |
