Compared with ordinary grinding media, zirconia grinding balls show prominent superiority in processing high-hardness materials such as lithium battery raw materials, ceramic powder, titanium dioxide and magnetic materials. Their ultra-high hardness avoids ball cracking and excessive wear during high-intensity grinding, extending service life 5-10 times longer than glass beads.
With high density and uniform sphericity, they provide strong impact and shearing force, realizing rapid ultra-fine pulverization and narrow particle size distribution. Meanwhile, the chemically inert property prevents metal impurity precipitation, ensuring high purity of finished materials.
This product is tailored for high-hardness material processing scenarios. It is extensively used for fine grinding of lithium battery positive and negative materials, electronic ceramic powder and nano-inorganic fillers.
It also applies to high-precision processing of high-hardness pigments, abrasive materials and pharmaceutical raw materials. In industrial mass production, it stably handles high-viscosity and high-hardness materials, effectively improving production efficiency and reducing equipment loss and production costs.
Yes. The ultra-high hardness and fine grain structure support ultra-fine nano-grinding, which can process high-hardness materials down to sub-micron and nano level with uniform particle size.
No. Made of high-purity yttria-stabilized zirconia, the balls are chemically inert with no metal precipitation, fully meeting the purity requirements of electronic and pharmaceutical materials.
Customizable sizes from 0.1mm to 25mm are available to adapt to different models of bead mills and ball mills, matching diverse processing demands.
Zirconia grinding balls feature extremely low self-wear. Their service life is typically 5 to 10 times longer than glass beads and 3 to 5 times longer than alumina media, significantly lowering media replacement costs.
They are compatible with high-speed pin-type bead mills, horizontal sand mills, vertical basket mills, and planetary ball mills, operating reliably under high shear stress conditions.
Store in a clean, dry environment away from corrosive chemicals. Clean thoroughly after use with a suitable solvent or water to prevent material residue buildup.
