How to Ball Mill Chemicals Safely — Skylighter, Inc.
Except for very small batches, ball milling is the best way for the amateur fireworker to reduce particle size in their chemicals. With small batches of individual chemicals, some folks use electric coffee mills to grind the chemicals into fine powder. NEVER grind mixed compositions in a coffee grinder, though. To do so would be to court disaster.

Planetary Ball Mills as an instrument Milling and Sizing
Chemistry can be divided in many different fields. Electro-chemistry and biochemistry are to be mentioned as an example. The beginnings of mechanochemistry can be traced to the start of the 19 th century [1]. The first studies were conducted by M. Carey Lea and focused on mechanically induced reactions of solids. Lea used a metal halide and processed it with a mortar: separating the metal and
Redox reactions of small organic molecules using ball
Mixing solid reactants in a ball mill is a promising means of avoiding the copious solvent waste associated with most chemical syntheses.
