activated alumina, pseudoboehmite, Zibo XiangRun Environment Engineering Co., Ltd.

Our factory manufacture 90%(92%), 95% and 99% alumina balls. It usually is used for grinding and packing material. It is called alumina ceramic balls or high alumina ceramic balls.

For grinding alumina balls, the main content is 92%(90%) and 95%; For packing alumina balls, the main content is 92%(90%) and 99%.

Our alumina ball is made of α alumina (α aluminium oxide--the most thermodynamically stable form) by cool isostatic pressing and fired at a very high temperature in the tunnel kiln. Our alumina ball product series include: alumina grinding ball for grinding, alumina packing balls and  inert alumina ball/ceramic ball for tower packing, catalyst bed support, column internals and catalyst carrier.

•  0.5-95mm

• high specific gravity and density, which significantly improve the grinding efficiency and extend the service life of the ball mill.

•  Low abrasion, corrosion resistance and wear resistance

• withstands high temperatures of more than 1,000ºC. It is resistant against acid, alkali and corrosion.
