Product Description

Product Description

Our Impact Resistant Grinding Media Balls, crafted with precision and excellence, come in two variants: the meticulously forged grinding balls, formed with the power of an air hammer, and the hot rolling balls, expertly manufactured using advanced skew rolling technology.
The utilization of state-of-the-art automatic production lines ensures that each ball meets exceptional standards, with quality control becoming ever more flawless and reliable.
This guaranteesconsistent size precision, unwavering hardness, and a uniform internal structure in every single ball.

Product Parameters

Achieving uniform hardness: an impressive range of 60-65 HRC
Minimized breakage rate: maintained below a remarkable 1%
Exceptional grinding resistance,resulting in a significant 10-30% extension of usage life
Outstanding high impact value: exceeding 14 j/cm²
Ensures high comprehensive efficiency within mills
