Our premium forged grinding balls are meticulously crafted using air hammer techniques, while our superior hot rolling balls are produced via innovative skew rolling technology, ensuring a top-tier manufacturing process.
Thanks to the implementation of cutting-edge automatic production lines, the quality control of our balls continues to reach new heights of perfection.
This guarantees the impeccable production ofprecisely sized balls with consistent hardness and a uniformly robust internal structure in every single ball.
Uniform hardness is maintained at an impressive60-65HRC, ensuring durability and performance.
Enjoy peace of mind with our low breakage rate, staying confidently
well below 1%, and experience significantenhancement in grinding resistance, extending use by 10-30%.
Our balls boast a high impact valueof over 14j/cm2, delivering unmatched strength and resilience.
They promise a high comprehensive efficiency of the mill, optimizing your operations.
