Ceramic grinding media consist of spherical or cylindrical ceramic beads and balls of high-performance materials. They are used in grinding machines, such as ball mills and sand mills, to break, disperse or ultra-fine grind materials by impact and abrasion. It is a critical component of a majority of industries that helps the final product achieve accurate particle size, purity and quality specifications.
Zirconia grinding media is a low-loss, high-strength and non-contaminating high-efficiency grinding solution. It solves problems like equipment wear, product contamination and inefficiency, providing high level of value.
① Low rate of wear prevents contamination, ensuring the ultra-high-purity material’s stable quality.
② High density of 6.0-6.05 g/cm³ increase grinding efficiency by 30%-50%, lowering production cycles.
③ Excellent compressive strength (≥2000 MPa) and shock resistance allow zirconia grinding media to endure high-speed grinding conditions without breaking.
① Media should be tougher than the material. For tough materials with high hardness, zirconia is ideal.
② For fine grinding, use small-diameter media; for coarse grinding, use large-diameter media.
③ For high-purity systems, use very low-wearing media. Zirconia is a good choice to achieve contamination-free grinding.
④ For grinding very viscous slurries, you need to use high-density media like zirconia to deliver sufficient kinetic energy and reduce equipment wear.
To minimize product contamination when grinding, you need to utilize low-wear media such as high-purity zirconia. Besides, you need to manage your production process carefully, complete washing all apparatus after every batch to prevent any cross-contamination.
It requires a combination of strategies: using high-hardness grinding media like zirconia or silicon carbide, operating high-speed mills with a high line speed to offer higher kinetic energy, and wet grinding with a dispersant to prevent agglomeration from heat. Efficiency is maximized through the balance of high-hardness, small-particle media with a high-speed wet-milling process.
