I think they meant the 1 pass looked OK and second pass looks pretty pulverized. For BIAB it would be OK, but husks are pretty shredded. (edit: probably workable on other systems if you baby it.)

The first pic I don't see any uncracked kernels. Sometimes they look mostly in tact but are really just held together with some husk.

It does look coarse for 0.028, but TBH that's why looking at the result yields more information than gap measurements.

Edit: I also get the impression that there are varying opinions re ideal crush. If you find a relatively fine crush works for you, then no reason to worry about it.

The gap on a 3-roller does not come out the same as a 2-roller, in my experience. I had both types for a while and used to compare them. The 3-roller had to be set wider to compare to the same setting on the 2-roller.
I set my 3-roller at .05 - .055, but I have a RIMS. My efficiency runs in the high 70's, low 80's consistently, except when I do a decoction, then it's the high 80's.
 
Just noticed your pics. The crush looks really good but I'm surprised that's with 0.028.

The measurement may be slightly off based on gauge R&R score. I doubt it is worthy of doing a full study, but it is worth considering that effect.
 
yep, I agree with mashdar on this.
I'm just gonna go with it. And do 2 passes on my first batch this weekend. I put the 028 feeler gauge in I didn't make it super tight on it. I just made sure it fit perfect. I could have tightened it so it was super tight. But pulling the feeler gauge out moves the setting a little bit.

Assuming you are measuring at each end and checking the clearance after everything is tightened back up.
Have you also checked after rotating the rollers 90 degrees etc to confirm concentric rollers? Also are the rollers loose in the bushings?
These mills aren't precision devices so I wouldn't expect perfection, but it might help to know if the gap is wider at any point of rotation.
Just a thought

I'm removing the hopper now gonna slide the 028 back in and turn and tighten down on the feeler as tight as I can and try to slide it out without loosening it up. And just be done with it. Lol. And I'll have to find the right setting with the warrior variable speed controller to where the drill gets it going. Bogs down but will not come to a stop lol. Trial and error. Especially first time

Has some dust but this is 028 remeasured tight on the feeler. A single pass

Def finer than yesterday's 028 double pass.

I'm brewing on spike solo biab. Except not using their basket. I had a custom one made from arbor fab

To my eye that looks pretty good, I don't think I'd go any finer.
Might be just a tiny bit of flour but I've definitely mashed like that and had no issues.

Yea thanks. I'm tired of second guessing

Ok thanks. I'm tired of second guessing and panicking. I'm going for it. Single pass only we'll see how the first brew goes for efficiency
 
That looks like any of my crushes now - and I run a 3v2p conventional herms, not a BIAB rig.
Everything I've read on HBT says "crush 'til you're scared" for BIAB. That crush wouldn't scare me at all...

Cheers!

Thanks we'll see how it goes. 70% efficiency is set in beersmith. We'll see what comes out of this crush
