Hammer mills run fast2400+rpm. You have got to get a way to speed up your pto speed(540 or 1000) to drive the mill. I'd look for a used grinder/mixer or figure on driving your mill with a flat belt from the pulley on your tractor. On grinder/mixers you'll see the expensive way the builders speed up the rpm, usually a big pulleysmall pulley ...

Hammermills are somewhat limited in the finished particle size that can be conveniently achieved. Typical finished ground product from a conventional hammermill set up will be in the range of 90 to 95% less than 30 mesh ( mm) with a mean particle diameter of 200 1/4 to 300 1/4. Specially equipped hammermills are capable of grinding ...

Just taking a wild guess that the mill pulley was 4" in dia and driven at 3000fps. That would calculate an shaft speed of 3140rpm. It would be safe to direct drive this unit with a 10 or 15/16HP 3450rpm electric motor. Handier and cheaper to run per hour than a tractor. If my math is correct.
