Wear-resistant alumina ceramic liner plates are specialty structural ceramic products manufactured from high-purity alumina (Al2O3) through dry pressing and high-temperature sintering at 1500–1700°C. The alumina content typically reaches no less than 92%, with 95% and above being standard grades. Typical technical specifications include: bulk density ≥3.6 g/cm³, Rockwell hardness ≥85 HRA, compressive strength ≥850 MPa, and fracture toughness KΙC ≥4.8 MPa·m¹/². The Mohs hardness reaches grade 9, second only to diamond. Product thickness ranges from 1.5 to 25 mm, customizable for various operating conditions.

The material exhibits significantly superior wear resistance compared to metallic materials. Laboratory wear testing (p=76N, n=800 r/min, t=30min) shows wear loss ≤0.0002g. Under actual operating conditions, its wear resistance is 260–266 times that of manganese steel and 170–171.5 times that of high-chromium cast iron. With a density approximately half that of steel, it effectively reduces equipment operating loads. The ground and finished surface is smooth and flat, offering non-sticking, non-clogging, and oxidation-free characteristics.

Wear-resistant alumina ceramic liner plates are widely applied in thermal power, steel, metallurgy, coal, mining, chemical, cement, and port industries, protecting material conveying pipelines, chutes, hoppers, cyclones, as well as pulverizing, ash handling, and dust collection systems subject to severe wear. Installation methods include high-strength adhesive bonding, rubber vulcanization compounding, and welding fixation. Pingxiang Chemshun Ceramics Co., Ltd, established in 2002, specializes in manufacturing wear-resistant alumina ceramic liner plates, tiles, high-alumina grinding balls, and chemical packing products, with an annual output of 5,000 tons. Primary raw materials are imported from Australia and France, with approximately 60% of products exported directly to European, American, and Southeast Asian markets. The company has obtained ISO9001, ISO14001, and OHSAS18001 management system certifications.
