Grinding RodsFor Rod Mills
High carbon steel grinding rods with excellent straightness, high toughness and wear resistance for stable rod mill performance and lower operating cost.
High HardnessWear resistance for longer service life
Good ToughnessResists breaking under bending stress
Strict Quality ControlFrom raw material to finished product
Support CustomizationCustom diameter, length and hardness
Product Overview
Grinding rods combine straightness, toughness and controlled hardness. Diameter, length and end condition are produced to fit the mill dimensions and reduce tangling during operation.
Material grade, heat treatment and final specification are matched to the mill condition and verified by batch inspection.
