Import 20x13 Mm Alumina Ceramic Grinding Column — Buy in wholesale FOB from Supplier in China

The 20x13 mm Alumina Ceramic Grinding Column is an industrial-grade ceramic component designed for high-performance grinding applications. This cylindrical grinding medium measures 20 mm in diameter and 13 mm in length, providing a compact yet efficient grinding surface for various manufacturing processes. The column is manufactured from high-purity alumina ceramic, typically containing 92-99% aluminum oxide content, which confers exceptional mechanical and thermal properties essential for demanding grinding operations.

The material grade used in this grinding column is typically 92-95% alumina (Al2O3) for general-purpose applications, with higher 95-99% grades available for more aggressive environments. The ceramic exhibits a bulk density of 3.6-3.9 g/cm3, depending on the specific formulation and sintering conditions. This high-density structure provides the column with exceptional hardness ratings (HRA 80-90) and outstanding compressive strength typically ranging from 200-300 MPa. The thermal stability allows operation at temperatures up to 1600-1700 degrees Celsius, making it suitable for high-temperature grinding processes in ceramics, metallurgy, and advanced manufacturing.

This grinding column serves multiple industries including ceramics manufacturing, electronics component production, metal surface finishing, and mineral processing. The product is commonly purchased by industrial grinding equipment manufacturers, ceramic tile producers, precision parts fabricators, and mining operations requiring durable grinding media. Trade terms typically include L/C and T/T payment options with flexible MOQ arrangements. Packaging is designed for industrial shipping with secure cushioning to prevent damage during transit. Buyers should verify specific dimension tolerances and surface finish requirements with the supplier before placing orders.
