A ball mill is a type of grinder used to grind and 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.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

One of the few things I had to buy for this project, aside from the casters, was the steel balls. I found these online. They were quite inexpensive. I went with 5/8 inch diameter balls, which seem to work well in a mill this size. I have been powering the ball mill with my bench variable power supply so I could fine tune the rotation speed.
