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.

Industrial mills are used to change the size of a product, whether by breaking or grinding a material into smaller granules or powder or by agglomerating a product into larger granules or pellets. Roller mills use rollers to crush the product into a smaller granule or powder. An attritor mill wears the product into a smaller size.
