Product Description

Industrial 35mm Ceramic Alumina Grinding Balls Beads for Ball Mill

High-Performance Alumina Balls for Industrial Grinding

Alu beads (alumina balls) are premium ceramic grinding media made from aluminum oxide (Al2O3), offering exceptional hardness, wear resistance, and chemical stability for demanding industrial applications.

Key Properties

High Hardness: Mohs 9 rating withstands high-pressure grinding environments
Superior Wear Resistance: Extended lifespan reduces replacement frequency
Chemical Stability: Inert material prevents contamination of processed materials
Thermal Stability: Performs reliably in high-temperature applications up to 1600°C

Key Advantages

• 99% Alumina offers 30% lower wear than 92% grade

• 2-5x longer lifespan vs. steel in abrasive slurries

• Harder than zirconia but more cost-effective for fine grinding

• Zero metal ion contamination (critical for Li-ion batteries)

Industry Applications

Industry	Benefit
Ceramic Industry	Efficient grinding of ceramic powders for high-quality products
Chemical Industry	Chemical inertness prevents contamination of compounds
Mining	50% lower replacement cost vs. steel in ore grinding
Paints & Coatings	Maintains color purity with no metal leaching
Pharmaceutical	FDA-compliant, no endotoxin release
