A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.

Balls are now produced by casting, die forging, and rolling. Cast grinding balls find a limited application. Hotrolled balls are produced according to a powerconsuming technology, as the ballrolling mill employs predeformed (rolled) billets. The process of ball dieforging is inefficient, as it requires great power and material consumption ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Casting the ball in epoxy was quite the journey. The plan was to do it in two steps. First, pour just enough to hold the torus in place. Then, pour the rest of the ball. The epoxy process was similar to the OOMOO (mix and combine in a specific ratio), but with the added step of using a vacuum pump to pull out air bubbles before pouring.

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.
