Import 20x17 Mm Alumina Ceramic Grinding Column — Buy in wholesale FOB from Supplier in China

The 20x17 mm Alumina Ceramic Grinding Column represents an optimized mid-size dimension for industrial grinding applications requiring slightly larger contact area compared to the 20x16 mm variant. This column measures 20 millimeters in length with a 17-millimeter width, providing enhanced grinding surface area while maintaining the compact form factor suitable for vertical and horizontal bead mills. The high-purity alumina ceramic body delivers exceptional resistance to mechanical wear and chemical attack, making it suitable for extended operation in aggressive processing environments. The product is manufactured through isostatic pressing to ensure uniform density distribution throughout the ceramic body, eliminating weak points that could lead to premature failure during grinding operations.

Material composition for this grade typically consists of alpha-phase alumina with sintering additives including magnesium oxide and silicon dioxide to control grain growth and improve thermal shock resistance. The resulting ceramic demonstrates excellent thermal shock resistance, capable of withstanding rapid temperature fluctuations without cracking or spalling. This property is particularly valuable in applications involving intermittent heating and cooling cycles. The column exhibits high corrosion resistance to acids and alkalis with pH ranges from 2 to 12, expanding its utility in chemical processing applications where aggressive solvents are employed.

Primary applications include glass grinding and polishing, ceramic glaze preparation, electronic component manufacturing, and mineral ore pulverizing. The construction industry utilizes these columns for processing cement additives and construction materials, while aerospace manufacturers employ them in grinding advanced ceramic components for turbine blades and heat shields. The supplier offers flexible minimum order quantities to accommodate both pilot-scale testing and full-scale production requirements. Export packaging follows industrial standards with reinforced cartons and palletized shipping, while trade terms include FOB Qingdao and CIF options for international buyers.
