Our main products (25MM-150MM Forged Grinding Steel Ball)
Production and Detection equipment
Specific characteristics of the Forged steel grinding balls:
1, The overall high hardness: the hardness can reach 55-67HRC, volume hardness reaches 50-63HRC, and the average
hardness gradient distribution.
2, The impact toughness can reach 12J/ cm .
3, Low broken rate: crush resistance is the general casting grinding ball 10 times, ball impact more than 20000 times the
number, the breakage rate of not more than 1%.
4, No deformation: Forged steel grinding balls not roundness from beginning to the end.
