Product Description

This is a custom-shaped, industrial-grade, wear-resistant alumina ceramic component. It features a fan-like, arc-curved geometry with a dense, smooth surface. Designed with both inner and outer radii, this shape is intended to fit against the interior walls of cylindrical or conical equipment—such as pipelines, cyclones, hoppers, or mixers—providing a protective, wear-resistant layer against high-speed operation or material erosion. It is specifically engineered for curved or circular surfaces subject to wear, serving as a classic, cost-effective solution for industrial wear protection.

Key Performance Advantages

  • Exceptional Wear Resistance: With a Mohs hardness of 8.5–9 and a Rockwell hardness (HRA) of ≥85, these components offer over 10 times the wear resistance of standard manganese steel, maintaining an extremely low wear rate even under long-term erosion by fine particles.
  • Superior Curvature Adaptability: The specialized fan-shaped profile allows for a perfect fit against curved surfaces—such as those found in cyclone separators, pipe elbows, and air classifier blades. When installed with staggered joints, they eliminate unprotected gaps, avoiding the poor fit and material buildup issues common with standard square lining tiles.
  • High Corrosion and Heat Resistance: Boasting a density of over 95%, these materials resist corrosion from the vast majority of acids, bases, and salts (with the exception of hydrofluoric acid). They can withstand long-term operating temperatures of up to 1500°C, making them ideal for complex, high-temperature, and humid environments.
  • Lightweight and Easy to Install: With a density of only 3.65-3.70 g/cm³—roughly half the weight of conventional wear-resistant steel plates—they significantly reduce the load on equipment. They can be easily installed using high-performance ceramic adhesive.

Application Areas

1. Powder and Material Handling Equipment
Used as wear-resistant liners for cyclones, silos, chutes, pipe elbows, and the interior walls of fans. They protect against erosion from materials such as quartz sand, mineral powder, ceramic powder, and cement, while minimizing both metal wear and metallic contamination.

2. Rotating Equipment and Curved Interior Surfaces
When assembled into a circular configuration, these fan-shaped segments serve as linings for the interior walls of mixing tanks, blenders, grinders, and centrifugal equipment, preventing the metal housing from being worn through.

3. Textile, Paper, and Packaging Machinery

Used as thread guides, scraper blades, pressure plates, and curved paper-handling segments. They reduce wear on metal components caused by fibers or paper, while simultaneously preventing contamination from rust. 


4. Electrical and Electronic Insulation Components

Used as insulating partitions or curved insulating supports in electric motors, transformers, and heating equipment, leveraging the material's high electrical resistance and heat resistance.

5. Industrial Furnaces and Thermal Equipment
Used as curved spacers, support plates, reflectors, or high-temperature isolation components within furnaces; suitable for oxidizing atmospheres and high-temperature environments.

6. Chemical Processing and Electroplating Equipment
Used as curved liners, pump casing linings, or protective inner walls for tanks in environments containing corrosive media; offers superior resistance to acids, alkalis, and corrosive gases compared to metals.

7. Semiconductor and Precision Equipment
When manufactured from high-purity alumina, these components can serve as wear-resistant, insulating parts within process chambers, gas flow deflectors, or protective elements around wafers—prioritizing low metallic impurity levels and the minimization of particulate contamination.

8. Decorative and Consumer Structural Components
Certain curved ceramic pieces are used in items such as watch cases, jewelry, lighting fixtures, and audio equipment enclosures, taking advantage of their bright white appearance, wear resistance, and hypoallergenic properties.
