In Reply to: rotor loss in barley posted by green convert on :

I found as well that I had to run my rotor at about 800 to 900 and the concave at about 4 to get min. loss. This was with completly worn out rub bars, 4 filler bars, and no mods however, and still cranked out a good 700-900 bu./hr with a lot less loss than my buddy's 9600 at a much lower rate. Should have no trouble doubling the green machine after some mods. I think the idea is to spread the material out as it goes over the cage not bunch it up like the extra deep helicals and discharge paddles are likely to do.
