Nwmo | hwd has it right. The way it was explained to me, rotor has threshing elements that protrude from the rotor tube about 5 inches. The distance between the threshing elements and the concave is supposed to be about the width of an average cob without corn on it. The rest of the rotor is going to be 5 inches plus the concave clearance distance away from the concave so its best to have that area filled with cobs so as the elements rotate the cobs rub together as well as squeeze between the elements to be threshed. If the rotor/cage is empty, cobs tend to be thrown around and broken up rather than threshed thus letting them slip through still on the cob.
In a walker machine, corn cobs can't get through the cylinder without being engaged by the concave no matter how full it is so its not as big of a problem.
