I was grinding barley in my blender when I got an idea for an upgrade.
The smallest particles of grain are quite airborne,  while the bigger bits still fall to the bottom of the pitcher.
The tiny finished product still interfered with the process.
I ended up sifting out the finished flour and returning the unfinished bits to the blender.
It was more work, going back a step in the process.
What if I could sort out the finished product as I went?
So,  if I introduced pressurized air through  a nozzle,  could I induce the finest bits of flour to leave via another opening?
I'm thinking a half inch cpvc pipe with an elbow at the end mated to an air mattress inflator.
The air is introduced about half way down into the blender,at the side, with  the elbow directing the air to form a vortex.
The outlet would be at the top of the blender,  with a large barbed fitting directing particle laden air to a food safe container, via a clear hose.

All penetrations would be via the lid, to avoid any issues with drilling glass.
With the blender already inducing a vortex,  it might be better to blow the air strait down into the grains.
The final food safe container probably should have a lid with a filter,  to release air and retain flour.

How much flour grinding do you think you'd like to do?

I wonder if a blender would get worn out for being used for this too much?

From what I read a while ago, stones do a better job at milling than metal blades. If you have a stand mixer, there are inexpensive stone mill attachments for these.

I have a stone-grinding grain mill and it paid for itself in less than a year because I bake lots of bread.

Neat idea William, I've never considered using the blender to mill whole grain. I was thinking how you said the lightweight pieces fly around and the heavier pieces stay at the bottom. I wonder, if bending the blades to reduce or practically eliminate the air vortices, and have an opening at the bottom for discharge, and proceed to add whole grain from the top. In the top, past the whirring blades, out the bottom. It may take a couple passes to get a consistent product, or possibly discover that this idea totally won't work.

The only blender I know of that works well for grinding grain, is the Vitamix, because the 'blades' aren't really blades, but essentially, hard metal blocks, that pulverize the grains, instead of chopping them. An actual edged blade will get destroyed by the hardness of the grains, pretty quickly, and the motor will burn out, in the effort. Typically, blenders are a fairly light duty item, with their most difficult tasks being chopping ice and pureeing fruits & veggies. Grains are a whole different ballgame. A Vitamix can even pulverize soap nuts - which is how I destroyed my last blender (oops!), which was a high powered one, but with sharp - edged blades. I can't recommend doing it.
