• Grinding Media

    In ball milling applications, the diameter of the balls, mill and throw action of the charge provides a low-impact environment– hence maximum abrasion resistance of steel balls is the desired characteristic. CHEMISTRY & HARDNESS High carbon content and high hardness levels affect abrasion resistance in steel balls.
