Our 99.5% High Purity Alumina Grinding Bead is a specialized milling medium engineered exclusively for pigment dispersion—addressing the critical challenges of pigment processing, such as preserving color accuracy (no impurity-induced color distortion), achieving uniform particle size distribution (to ensure consistent tinting strength), and minimizing wear (to avoid contamination of pigment pastes). Crafted from 99.5% high-purity alumina powder via precision manufacturing processes—including ultra-fine raw material screening (particle size ≤0.3μm) to eliminate color-altering impurities, isostatic pressing for homogeneous density (preventing uneven wear), high-temperature sintering (1700℃–1780℃) for full densification, and precision spherical polishing (sphericity ≤0.03mm) for smooth milling action—this bead delivers reliable, high-quality dispersion results for all types of pigments (organic, inorganic, metallic, and carbon-based).

Our Anti-Corrosion Ceramic Bearing Balls for Food Processing Machinery are engineered to address the unique challenges of food production—delivering food-grade safety, extreme resistance to corrosive food fluids, and compliance with strict hygiene standards for the critical bearings in mixers, conveyors, fillers, and slicers.

Our Bio-Inert Ceramic Balls are precision-engineered for critical medical device components, designed to meet the strictest biocompatibility, sterility, and durability standards of the healthcare industry.

Composition
The main component is Al₂O₃, the purity is more than 99.9%, and the impurity content is very low (such as Na, K, Si and other elements are usually in ppm). The purity of some products can reach 99.99%, and the content of radioactive isotopes (such as U and Th) is very low, which is suitable for scenes with strict purity requirements.

99% purity alumina grinding ball is a kind of high purity, high wear resistance ceramic grinding medium, widely used in chemical, electronics, ceramics and other industries fine grinding and dispersion. The following is its detailed introduction, parameters and uses:

Zirconium beads can be used to polish many products, polishing zirconium beads generally with 1mm, 2mm, 3mm or more of the beads, can be polished wheels, hardware, medical equipment, jade, rings, necklaces and gold and silver jewelry, in the mirror polishing of the abrasive surface finish requirements are high, abrasive surface to be smooth, can not have grinding force, so that it will not scratch the work. Zirconium beads and polishing liquid are vibrated together in the roller barrel, which can throw the jewelry very bright, eliminating the manual polishing procedure, saving time and effort.

The zirconia bearing ball is lighter than the steel ball, reducing the rolling and wear of the channel, the hardness is higher than the steel ball, the surface is smoother than the steel ball, the friction coefficient is smaller, the coefficient of thermal expansion is one quarter of the steel ball, can withstand large temperature changes, the steel ball will rust, but also need to add lubricating oil, but the zirconia ball will not rust, do not need to add lubricating oil when working, So now the slide rail and ceramic bearings are mostly used zirconia balls

Zirconia beads, the color of pearl white, smooth surface, in the ceramic ball is a very hard abrasive, long use time, durable. Zirconia ceramic grinding medium is often used for ultrafine grinding of heavy calcium carbonate, kaolin, mica and other non-metallic minerals.
