Grinding Ball | NSiC Grinding Ball | High Hardness & Wear-Resistant Silicon Carbide Ball
PRODUCT DESCRIPTION
The Silicon Carbide Grinding Ball is a high-performance ceramic grinding medium, primarily composed of silicon carbide (SiC). Wear-resistant ball offers exceptional hardness, outstanding high-temperature resistance, and excellent chemical stability. Wear-resistant ball is widely used in precision grinding and processing applications that demand high material purity, accuracy, and efficiency,wear-resistant ball is a key consumable for ultrafine grinding and surface treatment in modern high-end industries.
ADVANTAGES
Ultra-High Hardness & Wear Resistance: With a Mohs hardness of 9.2–9.3, the grinding ball exhibits superior wear resistance.Wear-resistant ball minimizes self-wear during operation, effectively preventing contamination of high-purity materials and significantly extending service life. Silicon carbide ball offers 3–5 times higher wear resistance than zirconia balls and 5–8 times higher than alumina balls.
Excellent Thermal Stability & Chemical Inertness:Capable of withstanding high temperatures, oxidation, and corrosion from acids and alkalis,silicon carbide ball performs reliably in harsh chemical environments.Silicon carbide ball ensures minimal contamination, with extremely low metal ion leaching (Fe <5ppm, Na/K <1ppm).
High Density & Efficiency: With a bulk density typically exceeding 3.1 g/cm³, the NSiC grinding ball delivers greater impact energy during grinding, enhancing efficiency by 30–50% and enabling the production of uniformly distributed ultrafine powders.
