The Rockwell hardness of alumina lining bricks is greater than 80 HRA. Its main material is alumina powder, which is then sintered at high temperature to form a texture similar to ceramics, hence the name "alumina ceramic." Its production process gives it excellent wear resistance and acid-alkali corrosion resistance.
The thickness of commonly used alumina lining bricks ranges from 40-90mm and is available in rectangular, trapezoidal, and irregular shapes. The thickness is mainly selected based on the size of the ball mill and the properties of the materials.
Alumina lining bricks are widely used in various industries such as chemical, ceramics, cement, and mining. Common applications include quartz sand grinding, kaolin, silica powder, etc. Suitable products should be chosen according to different industries and product requirements.
