I use an extra bucket, fill it about 1/3rd to start, rest it on about a 45° angle atop my bench, then mist the grain as I rotate the bucket along the bench top which folds some of the grain over as I go along. Then I stop and stir by hand before adding the next third. Repeat until done.
As for rusting: I always reserve roughly one pound of dry base malt and run that through the mill at the very end to wick out most of the moisture. Also, it is important to start milling without a lot of delay after the last of the malt has been wetted. All we're trying to do is make the husk flexible, which is essentially done in a minute or so. Definitely do not want to allow the kernel to dampen as that will lead to loading up the rollers. I made the mistake of waiting 15 minutes before milling once and had to totally tear the mill apart to clean the roller knurling. Don't do that
Cheers!
