In the mineral processing industry, grinding is not only one of the most energy-intensive stages, but also a critical determinant of recovery and product quality. As China's "dual carbon" strategy (carbon peak & carbon neutrality) accelerates, mining enterprises are seeking technologies that reduce energy consumption while maintaining process performance.
One promising path: replacing traditional steel grinding balls with advanced ceramic balls.
🔹 Why Replace Steel Balls?
Steel balls are dense and durable, but they bring several issues:
- High energy consumption due to heavy specific gravity
- Iron contamination affecting flotation
- Shorter service life and higher replacement costs
In contrast, ceramic balls offer high hardness, superior wear resistance, and chemical stability. Their lower density means less overgrinding and lower power consumption, especially in fine and ultrafine grinding applications.
🔹 Experimental Study: Converter Slag at Daye Noranda
In the study, partial and full replacements of steel balls with ceramic balls were tested in both laboratory and industrial settings:
- Lab Results: When ceramic balls replaced ≤40% of steel balls, grinding efficiency remained stable. Using 100% ceramic balls achieved similar fineness if the feed rate was reduced to 80% of that for steel balls.
- Industrial Trials: In a CSM-300 vertical mill, substituting 14% and 38% of steel balls with ceramic balls reduced power consumption to 89.9% and 79.6%, respectively, without affecting flotation reagent usage or copper concentrate grade.
This demonstrates that ceramic balls can significantly reduce mill energy consumption while maintaining product quality - a crucial advantage for sustainable operations.
