Ball mill is the key device grinding for crushed materials, which is widely used for are dressing and glass ceramics industries Such as cement, silicate product, modern building materials, refractory, chemical fertilizer, ferrous metal, nonferrous metals. It has both dry and wet types of grinding for various kinds of ore and other grind-able materials. A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.

A shell, balls, and motor are the essential components of a ball mill. It is made out of a hollow cylindrical shell (drum) with balls set on a metallic frame that allows it to revolve around its longitudinal axis. The shell’s axis can be horizontal or at a little inclination to the horizontal. It has a partial filling of balls. The balls, which can be made of chrome steel, stainless steel, or ceramic, are the grinding media. The balls, which can be of various diameters, take up 30 to 50% of the mill capacity, and their size is determined by the feed and mill size. The larger balls break down the coarse feed materials, while the smaller balls aid in the formation of the fine product by eliminating void areas between the balls. The weight of the grinding media balls is usually kept constant. The size of the balls is determined by the feed and mill diameter.
