Alumina Ceramic Ball Mill Lining Brick Introduction
Alumina ceramic ball mill lining bricks are used to line the inner shell of ball mills, thereby protecting the steel shell from the abrasive and often harsh conditions of the milling process. These bricks are made from high-quality alumina ceramic materials, which have excellent mechanical properties such as high hardness, wear resistance, and impact resistance.

Alumina Ceramic Ball Mill Lining Brick Application
Widely used in power plants, steel mills, chemical, rubber, and coating fields, is the ideal surface wear-resisting material for material transfer equipment in mining, iron & steel works, thermal &powder plants, mine, etc, also used in ceramic, glaze, paint, zirconium silicate, alumina oxide, quartz, silicon carbide, lime carbonate, and mechanical equipment accessories, can extend the operating life effectively.
Theoretically the life time of the alumina ceramic is about 260 times longer than that of manganese steel and 170 times longer than that of chrome steel.
Alumina Ceramic Ball Mill Lining Brick Property
High density, high hardness, low wear loss, regular shape, impact resistance, corrosion resistance, etc.
