Can I mill grain in a coffee grinder?
I purchased one of these conical burr coffee grinders  recently.
It works well for coffee beans, which it can grind down to a near-powder.
Question: Can it mill grain?
If not, why not?
Is it because the finest grind setting "espresso grain" would still be too coarse for flour?
Is it because the friction of a conical burr would expose the wheat to too much heat/friction? (And what would that heat do to the flour that, say, a stone (or other type of grain) mill wouldn't?)
I suppose I could just buy some wheat berries and try it out, but I'm curious.
What opinions ye?
(I recognize that it's not built for high-volume grinding. If it could work, I'd only use it for small quantities of grain for a levain (or single loaf quantities)).
