A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and 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.
#0183;#32;Tubular Mills, with balls as grinding media, are used for grinding lime stone, cement clinker, coal, iron ore and many other minerals. Majority of the ball mill applications are dry process, which means that the material to be ground are fed into the mill in dry condition and the product is dry powder..

Dry milling of grain is mainly utilized to manufacture feedstock into consumer and industrial based products. This process is widely associated with the development of new biobased associated byproducts. The milling process separates the grain into four distinct physical components: the germ, flour, fine grits, and coarse separated materials are then reduced into food products
