Wear-resistant alumina ceramic liners are engineered from high-purity alumina (Al₂O₃ ≥92%) and sintered at ultra-high temperatures to deliver exceptional hardness and structural integrity. With a bulk density of ≥3.60 g/cm³, a Rockwell hardness of HRA ≥80, and a flexural strength exceeding 300 MPa, these liners consistently achieve a volume wear loss that is only one‑fifth of that measured on standard Q235 steel under identical abrasive conditions, effectively extending equipment service life by 3 to 5 times.
These liners are widely deployed in coal-fired power plants, cement mills, steelworks, mining chutes, and pneumatic conveying systems, protecting high-wear zones such as hoppers, cyclones, fans, pipelines, and mill housings from premature failure. Their exceptional resistance to sliding abrasion, impact, and moderate thermal shock—capable of continuous operation at temperatures up to 1000°C—helps operators drastically reduce unplanned downtime, maintenance costs, and material contamination.
Installation methods are diverse and adapt to complex geometries: ceramic liners can be securely fastened with high-strength epoxy adhesive, countersunk bolts, or a combined mechanical‑chemical anchoring system, while custom‑engineered weldable steel trays with pre‑laid ceramic tiles are available for retrofitting existing equipment. Every liner is precision‑calibrated, with standard tile sizes such as 150×100×20 mm and 100×50×15 mm, and can be further machined into curves, tapered segments, or cut‑outs to match exact design drawings.
As a dedicated manufacturer and exporter of engineered ceramics, we enforce strict quality assurance protocols on every batch—from spray-dried powder preparation and high-pressure forming to precision kiln firing and automated dimensional inspection—ensuring consistent flatness and thickness tolerance within customer requirements. Paired with our application engineering support and global logistics network, you receive a truly dependable wear-protection solution.
