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.

At Carajas, the new grinding plant was operational in 2002, with two ball mill lines followed by a de-sliming plant. The closed circuit, wet grinding mills were designed to operate at 600% circulating load, in order to minimize the production of fine particles and consequently give increased recovery at the de-sliming plant.
