Microstructure (Typical)
High Chrome Cast Grinding BallsFor Cement Mills, Ball Mills & Abrasive Ore Grinding
High chromium grinding balls for fine grinding and abrasive ore conditions where outstanding wear resistance is the main concern.
Exceptional Wear ResistanceHigh chromium carbide matrix
High HardnessHRC 58-66 for excellent durability
Cost EfficientLower wear rate and cost per ton
Consistent QualityStrict process and heat-treatment control
Product Overview
High chrome cast grinding balls use a hard chromium carbide matrix to resist abrasive wear. Alloy selection and heat treatment are adjusted to the mill impact level and target service life.
Material grade, heat treatment and final specification are matched to the mill condition and verified by batch inspection.
