68% Alumina Ball 30-60mm In Creamic Industry For Grinding

Baiyun Middle Alumina Ball features:

1) Spheres (balls) or cylinders
2) Very excellent support and covering media
3) Function as support media for catalyst beds or other chemical beds in reactors or towers
4) Very excellent performances and stability in acid and other chemical surroundings
5) Very good chemical stability and low rate of water absorption
6) Can withstand high pressure and high temperatures
7) Can be even used in hot caustic service because they can resist over 10% sodium hydroxide service up to 60ºC, and 1% sodium hydroxide service temperature up to 100ºC
8) Can also resist the chemical corrosions of any acid (including organic and inorganic acids, but except HF acid), most of alkali and organic solvent
9) Will increase the distributors of liquid and gas, supporting and protecting the catalyst and avoid poisoned
