homemade ball mill

i hope this video helps those of you who need to make a ball mill or those of you who dont understand them at all.

what it does is the can is filled with about twenty 50cal. muzzle loading balls or brass media. the chemicals in black powder needing to be groung fine are put in. when the machine turns on, the balls pound the chemicals very fine. it usually takes about 6 hours for about 35 grams depending on media, canister size, and speed.

it can be used to chemically combine the ingredients in black powder too to make it faster too.

and it can roll stars also
