A 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.

As depicted in Fig. 1, preparing graphene by ball milling involves adding grinding aid (aluminum powder). After ball milling, the fresh aluminum surface is exposed to the air, where it easily heats and burns to produce impurities that are difficult to remove. Steel balls and sand mixed in graphene need to be removed by screening after ball milling.
