We had rotor running anywhere from 750 up to 1000 with little difference in rotor loss.
We have finished barley and now onto wheat with next to no rotor loss but 5 plus bars on the sieves, anything above 4 bars and there is a river of grain out the back. Got the top sieves on 25 (all the way open) and the bottom sieves anywhere from 10 to 14 depending on sample. Rotor on 950, fan on 1100 and concave between 6 and 15 depending on conditions. Can only get 65 tonnes per hour consistently, surely it should do more, I was hoping 80 tonnes/hr!!
