Product Description
Forged grinding balls are made by air hammer and Hot rolling balls are produced by skew rolling technology.
Because of automatic production lines are used, balls' quality control is increasingly perfect.
This makes sure precise size control, stable hardness, uniform internal structure for each ball.
Uniform hardness: 60-65HRC
Low breakage: below 1%
High grinding resistance: 10-30% longer use
High impact value: more than 14j/cm2
High comprehensive efficiency of the mill
