How to Make a Ball Mill: 12 Steps (with Pictures)
Let the mill run for a few hours. It takes time to grind up your chemical into a fine dust. Because the ball mill is quite loud, store it in a closet or the basement while it is running. Check on it periodically to make sure everything is running smoothly. After a few hours check the consistency of your chemical.

Ball Milling
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
