Wear Resistant Alumina Liner
Products Description
Our Wear Resistant Alumina Liner is engineered to provide long-lasting protection for equipment and pipelines exposed to abrasive materials such as ore, slurry, sand, coal, and industrial powders. Made from high-purity alumina ceramic, the liners offer exceptional hardness, impact resistance, and thermal stability-making them ideal for demanding environments in mining, power generation, steel, cement, and mineral processing industries.
By integrating alumina ceramic liners into your system, you significantly reduce equipment downtime, maintenance frequency, and operating costs, while extending the overall service life of critical components.
Key Features & Advantages
Extreme Hardness & Wear Resistance
Alumina ceramic reaches a Mohs hardness of 9, second only to diamond, delivering outstanding performance against abrasion, erosion, and material scouring.
High Structural Strength & Impact Resistance
Optimized ceramic pressing and sintering technology ensures excellent mechanical strength, making the liners resistant to mechanical impact and particle collision.
Excellent Corrosion & Chemical Resistance
Stable ceramic composition ensures reliable operation in acidic, alkaline, or chemically aggressive environments.
High Temperature Stability
Reliable performance at elevated temperatures commonly found in cement kilns, power plants, and high-pressure pipelines.
Customizable Sizes & Shapes
Available in blocks, tiles, cylinders, mosaic tiles, hexagonal tiles, and pre-shaped segments to fit elbows, cones, chutes, and complex geometries.
Long Service Life & Reduced Maintenance
Significantly extends equipment lifespan, reducing maintenance frequency and minimizing downtime-related losses.
Common Applications
Our Wear Resistant Alumina Liner is widely used in:
Mining & mineral processing – slurry pipelines, chutes, hoppers
Cement plants – separators, cyclones, clinker transfer
Power plants – ash handling systems, coal conveying lines
Steel industry – raw material handling, sintering systems
Bulk material handling – conveyor transfer points, feeder systems
Chemical industry – corrosive powder or particle transport
Cyclones, elbows, cones, mixing equipment
Whether for new installations or retrofits, alumina ceramic liners provide reliable long-term protection.
