ZrO2 grinding beads, also known as zirconia grinding media, are high-performance spherical grinding beads made from high-purity zirconia (ZrO2) with yttrium oxide as a stabilizer, through high-temperature sintering and precision shaping. Designed for ultra-fine grinding and dispersion of high-viscosity, high-hardness, and zero-contamination-required materials, these beads stand out for their exceptional hardness and wear resistance, making them an ideal choice for various industrial grinding applications that demand high efficiency and product purity.

High-performance Silicon Nitride Ceramic Balls deliver exceptional mechanical strength, lightweight durability, and thermal stability for precision engineering applications. These Silicon Nitride Ceramic Balls feature ultra-low friction, high wear resistance, and non-magnetic insulation, ideal for high-speed bearings, motors, aerospace components, and chemical equipment. Resistant to corrosion, oxidation, and extreme temperatures, Silicon Nitride Ceramic Balls extend service life under harsh dynamic loads compared to steel balls. Available in G3–G10 precision grades, polished surface ensures smooth rotation, reduces noise, and improves energy efficiency. Widely used in automotive, electronics, medical instruments, and industrial high-speed machinery.

High-hardness zirconium oxide balls, also known as zirconia grinding media, feature exceptional density, superior wear resistance, and chemical inertness. Made from high-purity zirconia ceramic, these beads deliver ultra-low abrasion contamination and long service life compared to glass, alumina or steel media. Their uniform roundness and smooth surface ensure efficient impact and shear force during wet and dry milling, dispersing nanoparticles evenly without discoloring materials. Ideal for high-viscosity slurries, pigments, inks, cosmetics, pharmaceuticals, ceramics, electronic materials and laboratory planetary ball mills. Corrosion-resistant and thermally stable, they reduce maintenance downtime while boosting fineness and batch consistency. Available in standard and customized sizes for industrial bulk production and precision fine grinding applications worldwide.

Food-contact grade zirconia beads serve as the core adaptive grinding media for the continuous ball milling process of matcha. Relying on excellent physical and chemical properties, food-grade safety characteristics and process compatibility, these beads have become a core consumable that balances production efficiency, food safety and matcha product quality. They are even the mainstream preferred grinding media for the current small and medium-scale industrial mass production of matcha (with a daily output of 100-500 kg), and their comprehensive performance is far superior to traditional non-food-grade grinding media such as alumina beads.

The density of zirconia beads depends on their zirconia content. Since zirconium has a high atomic mass, the higher the zirconia content, the higher the density of the beads. Yttria-stabilized zirconia beads typically reach a density of 6.0 g/cm³, stabilized with 5% yttrium oxide (Y₂O₃).

1.Impact Crushing: Directly break large materialsWhen the ball mill is running, alumina grinding balls rotate with the inner wall of the mill cylinder to a certain height, then fall or cascade freely under gravity.

The falling grinding balls produce strong impact force on the large materials in the cylinder, directly crushing them into smaller particles.

As a representative grinding medium for the latest generation of nanobattery materials, zirconia grinding beads offer the advantages of high density, high strength, good wear resistance and long service life. They enable nanoscale ultrafine grinding and dispersion of new energy battery materials.

Inert alumina balls feature high strength, high chemical stability, low water absorption and excellent thermal stability. They can resist high temperature, high pressure, and corrosion from acids, alkalis, salts and various organic solvents, and withstand temperature changes encountered in production.

3A molecular sieves are mostly used as catalysts and can also be applied in ethylene plant cracking gas dryers and air separation units. The particle size of 3A molecular sieves is generally expressed in "mesh", and they are commonly derived from their precursor, "zeolite".

The amount of water added to 5A molecular sieve depends on the moisture content of the product. Molecular sieves have a relatively high adsorption capacity, with a typical adsorption capacity of 22%.

There is a wide variety of alumina balls, and different types are applicable to distinct scenarios. For instance, activated alumina balls can serve as desiccants, while inert alumina balls are used as bedding and filling materials in hydrocracking refining equipment and catalytic reforming equipment. The Media Department of Moku Network will elaborate on alumina packing balls, a type of alumina ball.

Inert alumina balls possess the characteristics of high strength, high chemical stability, low water absorption, and thermal stability. They can resist high temperatures, high pressures, corrosion from acids, alkalis, salts, and various organic solvents, and can withstand temperature changes occurring during the production process. Widely used in petroleum, chemical, chemical fertilizer, natural gas, environmental protection and other industries, they serve as supporting and covering materials for catalysts in reactors. They can buffer the impact of liquids and gases entering the reactor on the catalyst, support and protect active catalysts with low strength, and improve the distribution of liquids and gases in the reactor.
