Description
1.GRINDING STEEL BALLS (STANDARD: YB/T 091-2005)
(1) Forged steel grinding balls:
Suit Equipment: both drying and wet ball mills
Tech Specs:
· The forged plant operates four production lines and sources input barstock directly from HM rolled grinding balls.
· It offers a hardness of ≈65HRc in surface, slowly decreasing towards the core.
· Diameters available: 20 - 15Omm (1½” --5″ ).
Key Benefits:
· Improved wear resistance due to quenching and tempering..
· Steady milling conditions due to wear reduction in wear rate.
It is the best-suited solution to fight wear: it is highly resistant to both abrasion and impact.
