92% Alumina Milling Media Balls - 5mm

92% alumina grinding media, 5 mm. High-purity alumina balls for general-purpose wet and dry milling. Significantly harder and stronger than standard 60% alumina media, with no zirconium content, making it the right choice when alumina is already present in your formulation or when zirconium contamination is a concern.

Technical Specifications

Applications

• Ceramics: body, glaze, and raw material grinding
• Minerals: quartz, feldspar, kaolin, and industrial minerals
• Chemicals and catalysts: bulk wet and dry milling
• Alumina-based formulations: where media wear does not introduce a foreign phase

Compatible Equipment

Ball mills, rod mills, horizontal mills, and attritors. Suitable for wet and dry milling.

Where Alumina Fits

Alumina is the most economical media in our range. It offers lower density than zirconium silicate or zirconia, which means less energy per impact and slower grinding in dense or viscous slurries, and it wears faster than stabilized zirconia. Choose alumina for cost-driven bulk grinding, or where alumina contamination is acceptable or already inherent to the product. For battery materials, electronic ceramics, or pharmaceuticals, use yttria- or ceria-stabilized zirconia.
