Import Alumina Grinding Ball — Buy in Bulk from Supplier in China

Alumina grinding balls from Shulei International are zirconia-toughened ceramic media designed for high-impact milling in ceramic, paint, coating, and mineral processing industries. The supplier’s source material specifies a dense structure that reduces wear loss during operation while maintaining grinding efficiency in ball mills. These balls are engineered to withstand prolonged use without compromising performance or requiring frequent replacement.

The composition integrates zirconia to enhance hardness, a typical approach in alumina-based grinding media to improve fracture resistance under heavy loads. Industry-standard alumina content for such balls ranges from 90 to 92 percent, with typical density values between 3.6 and 3.9 g/cm³. Surface finish and sphericity are controlled to tight tolerances, with common diameter ranges from 5 mm to 50 mm to suit different mill configurations and feed materials.

Industrial buyers use these balls in wet or dry grinding applications where contamination from steel media must be avoided. Common sectors include ceramic tile production, mineral comminution, and pigment dispersion. Bulk supply is typical for this product, with packaging often in 25 kg bags or 1-tonne big bags. Buyers should confirm diameter tolerances, wear-rate guarantees, and bulk density figures with the supplier to match their mill’s operational parameters.

Shulei International is based in Zibo, Shandong Province, a region known for its concentration of ceramic and grinding media manufacturers. The supplier operates as an imported-tier entity with a harbor trust classification, indicating established trade activity in the sector. Its address in Zibo 255000 places it within a key industrial hub for alumina products in China.

The company’s profile does not state a verified response rate or average response time, so buyers should directly contact Shulei International to confirm current stock, lead times, and technical specifications. No additional certifications, client references, or production capacity figures are provided in the available data, so these details must be requested from the supplier before placing an order.
