Performance Overview: High hardness intensity, excellent wear resistance, and applicable to all types of high shear energy sanding machines.
Ceria stabilized zirconia grinding media boasts one of the highest specific gravities (5.5 ~ 6.20 g/cm³). Based on kinetic energy principles (E=1/2mv²), utilizing ceria-stabilized zirconia media delivers greater impact energy, thereby significantly boosting production efficiency. This is especially advantageous for high-viscosity or abrasive products with high solid content. For lower viscosity formulations, choosing smaller Ce-stabilized zirconia media increases the grinding surface contact area, achieving superior dispersion results.
Featuring a delicate, uniform, and dense tetragonal microstructure, these ceramics possess gem-like hardness and high density among zirconium grinding media series. Their outstanding wear resistance and fracture toughness make them exceptionally suitable for ultra-fine grinding and pure dispersion of high-solid, high-viscosity, and high-hardness pastes, matching perfectly with high energy input and high-shear sand mills.
