The alumina balls are filled in ball mills over a fixed interval duration. The raw materials powder is mixed with the help of water in ball mills. The alumina balls crush the powder into a fine slurry while rotating in the ball mill. The ball mill mixing time is around 6 to 8 hr. Alumina balls are used in wet grinding as well as dry grinding.

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.
