The yield is lower, but the ease and speed more than makes up for it. To answer a few more questions, nozzleless rockets typically require faster fuels. Milled BP is sort of the standard. I personally don't believe a ball mill is NECESSARILY required for hot BP, but something of a comparable speed is required.

In Pokémon UNITE, Pyro Ball is Cinderace's first move. It is obtained by evolving from Raboot at level 7 and upgrading Ember into it instead of Blaze Kick.

Anyway it's a triple jar ball mill, each jar is about 1.3liters in volume so at full capacity it should churn out 600-700grams of high quality BP in a couple of hours. The motor was salvaged from a lathe and it has 400W power which is more than enough to rotate the three jars at 100RPM

You'd probably want to run at 'optimum speed' for dry powders, which is about 65% of critical speed. With the diameter of your media (1/2" balls ?) and the INTERIOR diameter of your mill jar, you can calculate the critical speed required, and the by multiplying this by 0.65, you'd arrive at a reasonably optimum speed.

Most Expensive / Best Way / Most Efficient: Buy a mill and a jar, and buy lead media. ($$$) FWIW: If you do buy a rock polisher online, make sure it's one you can modify (motor and rods) because they won't spin fast enough for efficient B.P. milling after your first or second time making B.P. (if it spins the mill with lead media at all)

Charcoal and potassium nitrate can be purchased pre-milled now, as well.
