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.

Milling was then performed in 80% ethanol for 30120 minutes using a highenergy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intrafibre swelling.

Mechanical Alloying. Oleg D. Neikov, in Handbook of NonFerrous Metal Powders (Second Edition), 2019 Abstract. This chapter introduces mechanical alloying (MA), which allows that the synthesis of novel alloys is not possible by any other technique due to the fact that MA is a highenergy milling process of powders mixing in the given proportion and phase diagram regularities do not act here.
