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.
Apr 26, 2019· Steel Grinding Media. Steel grinding media is used in mining where they are used to extract precious metals in ore mineral processing. Since ore particles must go through the grinding process, steel grinding media are ideal for such a grinding process. Steel ball grinding media are made from alloys of iron and carbon.
