High Alumina Bricks
Introduction
High alumina bricks is a high performance wear and impact resistant lining suitable for high impact, high pressure applications where tile may not have sufficient structural resistance and high performance rubber may not provide the required wear life. In extreme applications, Cube bushings can be installed in ceramic/rubber substrates or wear resistant steel plates, providing structural support to ceramic/rubber substrates and providing excellent wear life that competitive products cannot achieve.
Advantages
High Alumina Bricks use rubber as the bonding agent. The rubber is pressed around and between the alumina tiles and steel backing plate. The process of high pressure, heat and a superior bonding agent. This ensures removal of the alumina from the plate is virtually impossible.
Application
High Alumina Bricks have better wear resistance than metal materials and are easy to install. Has been widely used in iron and steel, thermal power, cement, coal, mine, port, chemical and other industries of material transportation equipment; Hopper, pipe, elbow, valve, fan blade, chute, ball mill, feeder, powder selection machine, ball mill and other anti-wear conditions. All kinds of alumina plate lining board and lining brick; We can design and produce arc, conical liner and special-shaped products according to customer needs.
