1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

We 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.

Spherical boron powders with sizes ranging from 4 to 100 μm were prepared by ball milling a commercial boron powder. A planetary mill was used with a process control agent consisting of two immiscible fluids: hexane and acetonitrile. The spherical powders formed when the volume of the loaded boron was close to that of acetonitrile in presence ...
