What is the difference between zirconia and alumina grinding media?

Yttria-stabilized zirconia beads typically have a density of about 6.0 g/cm³, compared with about 3.6 g/cm³ for high purity alumina. The higher density delivers more impact energy for fine and nano grinding with very low wear, which suits electronic materials, battery materials, inks and coatings. High purity alumina media are more cost-efficient and ideal where trace alumina is harmless, such as ceramics, glazes and alumina-based materials.

Which molecular sieve type should I choose?

4A molecular sieve is used for general gas and liquid drying and for removing water, ammonia and methanol from gas streams. 5A is used in PSA oxygen generators and normal-paraffin separation. 13X has the largest pore opening of the three and is used for air pre-purification (removing H2O and CO2) and as a catalyst carrier. Share your gas composition, pressure and dew point target for a specific recommendation.

What do G3 and G5 grades mean for ceramic bearing balls?

Ball grades defined by ISO 3290 and ABMA standards specify the allowable deviation in sphericity, diameter variation and surface roughness; a lower number means higher precision. G3 and G5 silicon nitride or zirconia balls are used in high-speed spindles, robotics joints, precision instruments and electric motors where low friction, electrical insulation and long service life are required.

Can you provide certificates, data sheets and test reports?

Yes. Copies of our management system certificates (ISO 9001, ISO 14001, ISO 18001) and CE documents, together with technical data sheets and batch test reports, are available on request. Email info@ball-tec.com with your application, size range and estimated quantity.

Where is your factory and do you support custom sizes?

Our 100,000 m² production base is located in the Ceramic Industrial Park, Development Zone, Pingxiang, Jiangxi Province, China, one of the country's leading industrial ceramic clusters. Custom diameters, compositions and packaging can be discussed directly with our engineering team.
