Ball mill. Ball mills (Fig. ) are short cylindrical vessels with a shell to diameter ratio of to 1 and less. When the length to diameter ratio varies between 3 and 5 it is called tube mill. The grinding medium is highcarbon or cast alloy steel balls.

Right now, your RPM is just slightly under the speed where the media won't do any work. The optimum speed for your jar to turn is around 90 RPM like Frozentech said.

I used to use a coffee grinder however the last time I milled some I resorted to a mortar and pestle instead, which was far too much work. I know ball milling is the most common for large quantities.
WhatsApp: +86 18838072829Lloyd Sponenburgh, in his Ball Milling Theory and Practice for the Amateur Pyrotechnician, tells us his explorations into ball milling began when he was faced with having to do all that grinding with a mortar and pestle to achieve small particle size and intimately mix his chemicals.

WhatsApp: +86 18838072829To make a very clear point, you should NEVER mill a live (burnable) composition, other than black powder based compositions. This does include charcoal stars as Mumbles mentioned, as they contain the same basic chemicals, but in a different ratio. If you are not aware, that includes Potassium Nitrate (KNO3), Sulfur (S), Charcoal ©, and the ...
WhatsApp: +86 18838072829A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

The ball milling times used were 10, 20, 45 and 90 min without interruption into an agate cup sealed in air. During the milling, three agate balls were used: the weight of agate balls to carbon material ratio was about 14:1.
WhatsApp: +86 18838072829We routinely recommend two ways: coffee milling and ball milling. Both ways have advantages. To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour.
