Forged steel balls are widely used many areas, such as large-scale mines, gold mine, copper ores, alumina ores, iron ores, metal ores, metallurgical mines, cement building materials, power plant, etc. There are three types for forged grinding balls. They are C grinding ball, Mn grinding ball and special alloy grinding balls. All the balls have the characteristic of high hardness, little breakage and good wear resistance.
