Default Help evaluate my crush

I've got a corona mill that I'm trying to dial in. Any input appreciated.

looks like a few grains are still intact. I'd go tighter. Go til you have no whole grains.

Not bad, but yes I'd go a little smaller. Ever thought about conditioning your grain?

I'd read a reference to it here, but no, I had not previously thought about it. I take it you recommend the practice?

Would it be OK to condition tonight and brew tomorrow (i.e. does that affect the grain's freshness)?

Yes I recommend it. It's pretty simple and almost always increases your efficiency. Also, you can condition the grain tonight and crush tomorrow. Just make sure that you cover the grain overnight.

Keep tightening until you've gone too far, then dial it back just enough. The size of the husk pieces is what you're looking at; you need to have those big pieces of husk to act as a filter. Conditioning helps you crush even finer without shredding the husks. Braukaiser.com has a great write-up on the process.

I think I'm set at 0.035 now. Somewhere in the 0.032 to 0.035 range should work well, I also condition a few minutes before I crush.

Same here.
0.035 is my sweet spot, good efficiency and no circulation issues on my HERMS with false bottom made from keg top, I am also conditioning..
I could try to tighten it a bit but I wouldn't go lower than 0.030, at least with my equipment.

As for your crush, you can tighten it some more (depending on your FB). Get yourself feeler gauges, they are not that expensive and you'll be able to set it precisely.

He has a corona mill. No numbers to set. Buying feeler gauges would defeat the purpose of buying a cheap mill. Just keep playing with it until it looks right.

This! It really is this simple IME and IMHO. FWIW my crush is a good bit finer than the pics.
