Applications and Selection Guidelines for Wear-Resistant Balls
Apr 02,2026
Wear-resistant balls are widely used in the following industrial sectors:
Mining and Metallurgy: Crushing and grinding of ferrous metals (iron, manganese) and non-ferrous metals (gold, copper, nickel, aluminum).
Building Materials and Cement: Grinding of cement clinker, slag, and fly ash; high-chromium balls have demonstrated significant benefits in increasing production and reducing energy consumption in this sector.
Power and Chemical Industries: Coal pulverization for thermal power plants, grinding of water-coal slurry in coal chemical processes, flue gas desulfurization, etc.
New Materials: Ultra-fine processing of silica sand, calcium carbonate, magnetic materials, and others.
Selection Recommendations:
Impact Toughness Priority: For semi-autogenous mills with large diameters and high impact forces, forged steel balls or high-toughness bainitic ductile iron grinding balls should be prioritized to prevent breakage.
Prioritizing Wear Resistance: For grinding high-hardness materials such as cement clinker, high-chromium alloy cast balls (HRC ≥ 58) typically offer the best cost-performance ratio.
Energy Efficiency Considerations: If energy savings and reduced consumption are the goals, lighter-density aubé balls (CADI) can lower power consumption and equipment load.
