Judith,
Hammer mills pulverize material to a very fine consistency. I would imagine a hammer mill would make paper and cardboard into a fine particulate material similar to the blow-in insulation that Spaceman just showed us in his short video. Hammer mills can be adjusted for the output size but they really are for making powder output.
Pellet mills use hammer mills to prepare the chips or sawdust to an even consistency before sending the raw material through the collets to make the pellets. It may be a very good application for papercrete, although we all talk about the fiber size and the strength afforded a longer fiber. It may make for an easy mix but may suffer in strength.
I'd say get it working and run some test batches with the results. It should be as good and as strong as that which a good tow mixer whips up.

I got this question the other day and have no experience or knowledge of hammer mills. Can anyone here help?
Hello Judith
Thank you for taking the time to write me with your thoughts :)
If you don't mind would you elaborate on a few ideas i have.?
As to the cardboard, since i posted forum piece i realized i have
a PTO Hammer Mill here, it hasent been used in along time, but if
it is operable, would running the cardboard through it to mulch/shred/grind
it help with the cardboard not being fine enough?
