  • Production Line

    Forged steel balls production line


    1. All the raw material-steel rods are produced by reputable large scale steel mills. We can also arrange special 

    processing for different requirements of the steel raw material . 


    2. We use an electric furnace to heat the raw material, in order to make sure all the materials can reach the correct temperature and reduce unnecessary loss during heating.


    3. To obtain high hardness,strength,toughness and superior wear resistance ,the forged steel balls undergo heat 

    treatment, water quenching, and tempering.


    4.During the heat treatment, we use advanced Isothermal temperature control technology, to insure the uniformity

     of the hardness of the grinding balls.

    Cast Balls Production line


    1. We use high quality alloy iron and carbon steel scrap iron as raw material,and a medium frequency  electric  furnace for smelting. The chemical composition and optimal proportions are created by our technicians through   continuously testing. 


    2. The hardness and toughness of the cast iron balls achieve the best conditions because of the best  configuration of the different chemical elements.


    3. Oil quenching and air quenching are the client’s option for the heat treatment process. Regarding the tempering process,we use the professional desktop tempering furnace to acquire the desired combination 

    of strength and toughness. Our cast iron balls have the advantages of low breakage, low wear rate and  no distortion.
