Product Description
Zirconia Alumina Composite Lining Brick is an important wear-resistant material, its main components are alumina and zirconia. Alumina has extremely high hardness, corrosion resistance and high temperature resistance, and ceramics are sintered at high temperature, which has excellent wear resistance and good chemical stability.
The composite lining bricks play an important protective role in the inside of the ball mill, which can effectively extend the service life of the ball mill. Its wear resistance is much higher than that of traditional metal materials, and it can be subjected to long-term continuous ball milling processing without adverse reactions, making the quality of the product more stable, with high economic benefits and social value.
Advantages
One of the most significant advantages of Zirconia Alumina Composite Lining Brick is their exceptional wear resistance. They are highly resistant to abrasion, cracking or chipping, reducing the need for frequent maintenance and replacement. This makes them a cost-effective solution for industrial applications where wear is a common problem.
Additionally, Zirconia Alumina Composite Lining Brick offer superior thermal shock resistance, which means they are less likely to break or crack when exposed to rapid temperature changes. This is an essential feature for applications where temperature variations are frequent, such as blast furnaces and steel plants.
Applications
1. Concentrator plant: lining brick for ball mill, sand mill, screening machine and other machines.
2. Iron and steel smelters: for linings and outer linings of blast furnaces, ladles, converters and smelting pools, as well as linings for pipes and kiln linings for drying furnaces.
3. Power plants: linings for coal-fired, gas-fired and oil-fired boilers, bellows, dampers for ash removal systems and liners for stackers.
