Product introduction:
Wear resistant alumina lining brick is also called alumina ceramic lining brick, ball mill lining brick, ball mill lining plate, wear-resistant ceramic lining brick, etc. It has the characteristics of high hardness, high density, low abrasion, good regularity and corrosion resistance. It is mainly used in the wear-resistant lining of the ball mill, and it is a powerful assistant for wear-resistant and corrosion-resistant of the ball mill.
Advantage:
Uniform size, it can be used with sub and female buttons or matched with each other, effectively isolating the contact surface between equipment and materials. Under the same conditions, the wear amount is only 1 / 260 of manganese steel and 1 / 170 of high chromium cast iron. The whiteness is good and will not pollute the quality and color of the ground materials. It has high hardness and good impact resistance, and can be used for wear-resistant lining of hard materials. The chemical property is stable and the acid / alkali corrosion resistance is good. It has good thermal stability and can be used in high temperature environment.
