Do any online vendors mill grain at a .025" gap??

How do you explain the benefits of double crush when someone asks "how can double crushing grains help when it uses the same roller gap on the second pass?" I've been ordering double crushed grains for years but logically when asked by someone at the LHBS it doesn't make sense.

The only proper response to the LHBS asking the above question:

"Why don't you improve customer satisfaction by closing your mill gap so that we won't feel any need to double crush?"

No real explanation to the second pass on a double crush other than doing it myself on my Corona mill. It IS a lot finer after the second pass.

The grain particles may enter the mill under a different orientation and get crushed more, they may also get crushed further against one another.

We are not talking about marbles falling gently through a sieve, but rather a bunch of particles being punished, crushed and sheared together between two very hard surfaces.

Crushed grain is friable, I would guess a 3rd and 4th pass would further obliterate it to an overall finer crush.

Slamming your hand twice in the car door likely hurts more than slamming it once I would guess lol
