High alumina bricks, also known as alumina lining bricks, are a type of ceramic bricks specially designed and produced for the lining of ball mills. This series of products is made of high-quality raw materials such as kaolin, sintered mullite, and alumina. Alumina lining bricks are ideal materials for ball mills because of their high hardness, high pressure resistance, and high temperature resistance.
There are many factors that make alumina lining bricks suitable for ball mills:
1. Wear resistance: Compared with other materials often used in ball mills, alumina lining bricks have high wear resistance. Compared with manganese steel, its wear resistance is 266 times that of manganese steel.
2. Corrosion resistance: Alumina lining bricks have strong resistance to acid, chemical corrosion, and abrasion of impellers. This is mainly due to the thicker brick structure and higher alumina content.
3. High density: Bricks lined with alumina are not easy to break because of its high density. This makes it suitable for ball mills and other high-vibration occasions.
4. High temperature resistance: Alumina lining bricks are resistant to high temperature impact and will not crack. This is because alumina has high thermal conductivity and small thermal expansion.
5. Smoothness: The surface of alumina lining bricks is smooth, which can effectively reduce the wear and friction between the liner and the abrasive medium. Reduce the wear rate and increase the service life of the ball mill.
In short, alumina lining bricks are widely used in ball mills due to their smooth surface, compactness, wear resistance, corrosion resistance, high temperature resistance, etc. As long as they are properly installed and maintained, they can extend the service life of the ball mill, improve production efficiency, and reduce production costs.
