As for Rod Mills, the image above best expresses what is going on inside. As rocks is feed into the mill, they are crushed (pinched) by the weight of its 3.5" x 16' rods at one end while the smaller particles migrate towards the discharge end and get slightly abraded (as in a Ball Mill) on the way there.

Ball mill. A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.
Lead usually won't spark in a ball mill( it would take quite a lot of abuse & extraordinary circumstances for it to become a possibility). when hardened with antimony it is a rather good choice for your needs, assuming a negligible amount of lead is acceptable. Mind the usual hazards with lead & such.

Lead balls, explosion proof electrical, and out in an open field a hundred feet away from anything you dont want to blow up I understand. Has any one done this and does it turn the powder into unusable dust. Of coarse there are always the wrong way of doing it and messing up. Screens shouldn't be a problem though and etc. for grading out correctly.

filled with lead balls described by George Weingart in his book Pyrotechnics, but such a milling contraption seemed to be excessive for a small scale hobbyist. With the better understanding of ball milling brought to the hobby pyro community by Lloyd's research in the mid 90s,
A ball mill is a rotating drum with dozens of lead balls inside. The 3 chemicals are loaded into the ball mill, along with the lead balls, sealed shut and allowed to rotate for anywhere between 1 and 24 hours. As the ball mill rotates, the lead balls will crush the chemicals together, forcing some of the potassium nitrate into the pores of the ...
