Description
High wear-resistant alumina ceramic lining bricks are mainly made of high-quality alumina powder with high purity. They are made by sintering in high-temperature kilns. They have uniform internal and external structures. Compared with other materials, they have higher hardness and good wear resistance, which can extend the service life of the machine. They have low wear, high density, and corrosion resistance. They are also called 92 lining bricks and ball mill linings.
Features of the High wear-resistant alumina ceramic lining bricks
1. The main component of the lining brick is high-quality alumina with high purity to avoid contamination of the grinding material.
2. Its hardness is superior, Rockwell hardness HRA ≥ 85, and the hardness is only lower than that of diamond materials. It can operate normally under harsh conditions.
3. Compared with traditional wear-resistant materials, it has higher wear resistance, which can reduce the replacement of equipment and extend the service life of equipment.
4. Alumina wear-resistant bricks have high temperature resistance and corrosion resistance, and stable chemical properties.
It has high compressive strength, the structure can remain intact under high-intensity impact, and has strong anti-stripping properties.

Applications
1. Because it does not react easily with other chemicals, it can be used in the chemical industry.
2. Due to its high hardness and wear resistance, it can be used in high-wear environments such as mining and material handling.
3. It is also widely used in heat treatment equipment such as furnaces and kilns.
4. It is also used in metallurgical industrial furnaces, heat treatment furnaces, construction industrial furnaces, waste incinerators, as well as cement, paint, pigments, pharmaceuticals and other industries.
