Import 20x48 Mm Alumina Ceramic Grinding Column — Buy in wholesale FOB from Supplier in China

The 20x48 Mm Alumina Ceramic Grinding Column is a cylindrical grinding media measuring 20mm in diameter and 48mm in length, manufactured from high-purity alumina derived from Shandong Aluminum base material. This grinding column features high strength, high hardness, and high wear resistance characteristics that make it suitable for intensive grinding applications in ball mills, can-type mills, and vibration mills. The cylindrical shape provides efficient grinding action with large specific gravity and small unit size, maximizing the grinding media-to-material ratio in processing vessels.

The grinding column is produced using high-purity alumina powder from Shandong Aluminum as the base material, which ensures high purity with minimal impurity content and consistent quality. Production follows kanban-based manufacturing with controllable and traceable processes throughout, and each batch undergoes strict quality testing to verify composition, density, and wear resistance parameters. The material exhibits superior wear resistance compared to common ball stones or natural cobblestones, providing significantly higher crushing and milling efficiency in fine grinding operations.

This alumina grinding column is widely used for precision processing and deep processing of ceramics, enamels, glasses, and thick hard materials in chemical factories and industrial mineral processing facilities. The primary buyers include ceramic manufacturers, glass processors, enamel producers, and mining operations requiring fine grinding of hard materials. The grinding media offers pollution-free operation as it does not introduce iron or other metal contamination into the processed materials, which is critical for white ceramic and glass grinding applications where color purity must be maintained.

Zibo Win-Ceramic Material Co. Ltd is located in Zhangdian District, Zibo City, Shandong Province, China, at No.22 Changguo Western Road, postal code 255000. The company specializes in ceramic materials and grinding media production, with manufacturing facilities in Shandong Province, a region with established alumina and ceramic industrial infrastructure.

The listing shows a harbor trust tier classification with a response rate of 0.00% and zero average response hours, indicating limited recent platform activity. The source description emphasizes the use of Shandong Aluminum base material, kanban production methodology, and batch-by-batch testing, but does not specify MOQ, pricing, lead times, or export certifications. Buyers interested in this product should directly verify current production capabilities and quality management system certifications.
