Alumina Ceramic Lining Brick
Wear-resistant ceramics are alumina ceramics made of AL2O3 as the main raw material, formed by dry pressing, with rare metal oxides (yttrium oxide, rare earth, etc.) as the melting agent, and roasted at 1700℃.
Alumina ceramic lining bricks are divided into rectangular lining bricks and oblique lining bricks according to its shape, which are mainly used in ball mill as lining.
Alumina ceramic lining bricks are used in various industrial machinery and equipment to prevent wear and tear on equipment and pipes.
PRODUCT DESCRIPTION

Product Description

Wear-resistant ceramics are alumina ceramics made of AL2O3 as the main raw material, formed by dry pressing, with rare metal oxides (yttrium oxide, rare earth, etc.) as the melting agent, and roasted at 1700℃. 

Alumina ceramic lining bricks are divided into rectangular lining bricks and oblique lining bricks according to its shape, which are mainly used in ball mill as lining.

Alumina ceramic lining bricks are used in various industrial machinery and equipment to prevent wear and tear on equipment and pipes.


High hardness

It has a Rockwell hardness of HRA 80-90, second only to diamond in hardness.

 

Smooth surface

High alumina ceramics have smoothness and adhesion properties, and their roughness is only 1/6 of that of steel pipes, so they have less flow resistance.

 

Corrosion resistance

High alumina ceramics are inorganic oxides with an extremely stable molecular structure and no electrochemical corrosion, so they are resistant to acids, bases, salt solutions and organic solvents.

 

Light weight

The weight is only half that of steel, so the equipment load can be greatly reduced.

 

Excellent wear resistance

Its theoretical wear resistance is equivalent to 260 times that of manganese steel and 170 times that of high chromium cast iron.
