A Gold Mine in Namibia, Africa - Magotteaux Forged High-Chromium Balls Optimizing Grinding Costs

The SAG mill had high grinding media consumption and easy deformation and breakage of steel balls, requiring lower Total Cost of Ownership (TCO).

Through mill working condition research and laboratory analysis, Magotteaux customized high-impact resistance forged high-chromium balls and optimized alloy composition.

4-month industrial application and data tracking.

• Steel balls wear evenly from 4.5 inches to below 0.5 inches without deformation or breakage, with a 40% reduction in wear rate.
• Improved grinding efficiency, 8% increase in ore processing capacity and reduced reagent consumption in the downstream process.
• Extended grinding media replacement cycle, less maintenance downtime and 25% lower comprehensive costs.

Proprietary alloy formula and database, adapted to high-impact working conditions and extended service life.
