Our high-performance Forged Grinding Balls are meticulously crafted using advanced air hammer technology, while our Hot Rolling Balls are engineered through innovative skew rolling techniques. This cutting-edge skew rolling technology ensures optimal durability and efficiency.
Thanks to the integration of state-of-the-art automatic production lines, the quality control of these balls has reached unparalleled levels of perfection. This guarantees
precision in size control, exceptional stability in hardness, and a uniform internal structure for every single ball.These attributes culminate in a superior performance that meets the most demanding industry standards.
Remarkably even hardness: Rated between 60-65HRC for consistent performance.
Exceedingly low breakage rate: less than 1%.
Superior grinding resistance: Extends product utility by 10-30%, ensuring prolonged operational lifespan.
Exceptional impact value: Surpassing 14j/cm2, offering robust resilience.
Elevates the mill's comprehensive efficiency, maximizing productivity and output.
