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.

To use the Mill, the material to be ground is loaded into the barrel which contains grinding media. As the barrel rotates, the material is caught between the individual grinding media balls which mix and crush the product into a very fine powder over a period of several hours. Quite simply, the longer the Ball Mill is run, the finer powder will be.

Ball Mills In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
