Detailed Description

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.
