When you say fines I assume you are talking about kernels of corn ground up. On a trip last week I reduced the fines, and broken kernels, by leveling the concave. Run the concave up to 0 while rotating the cylinder until it ticks. Check the back of the concave for level from side to side. Check the front of the concave through the rock door. If the concave is not level it will grind the corn and produce fines. I usually run the concave at 10, cylinder speed 300, front of the concave dropped down 2 marks towards MAX. Air at 7. chaffer at 1_2". Seive 5_16 to 3_8".If you have a hugger corn head install the hopper slope kit. A lot of broken kernels start at the front of the feed chains.
