burr/plate grinder for livestock feed,

I have been feeding millet (proso) grain to my goats, (bird seed the little white seed found in many bird seeds), we can raise it and the current price is low,

any way it is a small hard seed, and passes nearly though them, (it will germinate) so my  guess is there not getting that much out of it, and have considered getting a bur mill to grind it some,
the feed mill says there roller mill will not crack it to small of seed

any one have any experience with burr mills? and grinding feed for animals?

this guy found that a burr grinder wasn't the best solution for mesquite flour...not completely sure that's relevant.

If you don't need to use the seeds in huge quantity, don't mind some loss of calories, and can be sure that mold doesn't become an issue, you might try sprouting them.

And I say this too often, but a rolling mill can do a lot of things, and most of those it consumes less energy to accomplish than any alternative. You'd need a fairly precise one to crack open millet, so it may not be cost-effective.

the problem with the roller mill is the one the feed mill owns will not close up tight enough to do millet, I ended up making a burr mill with 6" burrs, I bought from CS Bell, used in there La Milpa mill, 


since the picture a belt guard has been added and the proper switch (the original switch was faulty),  and the frame was painted,  It grind about 10 pounds a min.
