All round steel bars used for the production of forged steel balls are sourced from State-owned standarded steel groups near our factory.
All ShengYe forged grinding media are manufactured to international quality standards and the processes include a quench & temper stage for improved hardness & toughness, providing for excellent impact and wear performance.
Our Forged Ball Plant operates 10 production lines, with all products being manufactured to national and international standards.
Smaller, roll formed balls from 20mm-70mm are manufactured on our state of the skew roll-forming machine and are fully heat-treated. Larger balls from 80mm to 200mm are produced by an upset-forge process with in-line tempering. The processes all include the heat treatment cycle for improved toughness and hardness.
