How to keep from grinding it up so much? I think I've got it looking pretty good but then in the bin it's a different story. I've played around with the rotor speed and concave. I'll find the correct concave clearance and then adjust the rotor accordingly. I've also slowed the rotor clear down to 300 and tightened way down to 25, but that takes more power and am not convicned it does a better job. Just venting..
