  • Isothermal Holding System for Forged Steel Balls Before Quenching

    Our isothermal holding system is a key intermediate process between steel ball rolling forming and quenching. It maintains constant temperature for forged balls to balance internal metal structure, release forging stress, and avoid deformation or cracking during subsequent quenching.

  • Steel Ball Rolling Machine for Forged Grinding Balls Production

    Our steel ball rolling machine is the core forming equipment for forged grinding ball production. It works perfectly with medium frequency heating equipment to roll heated steel blanks into standard round forged balls. This precision rolling process ensures excellent roundness, uniform density, low breakage and high wear resistance of finished grinding media.

  • Medium Frequency Induction Heating Machine | Forged Grinding Balls Production Equipment

    Our medium frequency induction heating machine is the core heating equipment for forged steel ball production. It rapidly and uniformly heats raw steel bars with precise temperature control, ensuring consistent forging quality, high roundness and stable hardness of finished grinding balls.

  • Grinding Balls Quality Control

    At ZONAI, our Grinding Balls Quality Control system is the backbone of our manufacturing process. We don’t just produce steel balls; we engineer precision tools for your mill.
