Ceramic Balls Product Overview

Material Composition:
92% Al₂O₃ (Alumina) ceramic grinding balls are high-purity, wear-resistant media designed for use in ball mills. The remaining 8% typically consists of other oxides (e.g., SiO₂, Fe₂O₃) to enhance sintering and mechanical properties.

Manufacturing Process:
Produced via high-temperature sintering (1600–1750°C) of fine alumina powder, these balls exhibit high density, low porosity, and excellent mechanical strength.

Advantages for Ball Mill Applications

High Wear Resistance:
The 92% Al₂O₃ composition ensures minimal abrasion, reducing contamination of the milled material and extending media lifespan.

High Density & Grinding Efficiency:
The dense structure (3.6–3.7 g/cm³) provides superior impact energy, improving grinding efficiency compared to lower-density media (e.g., zirconia or steel).

Chemical Inertness:
Resistant to acids, alkalis, and organic solvents, making them ideal for reactive or corrosive materials.

Low Contamination:
Suitable for ultra-fine grinding of pharmaceuticals, electronics, and ceramic powders where purity is critical.

Cost-Effective:
Longer lifespan and lower replacement frequency compared to steel balls, reducing downtime and maintenance costs.
