High Quality Activated Alumina Ball with High Crushing Strength
High alumina ball is made from industrial alumina and processed by shaping and firing, which has two types according with main application, one is Chemical industry corundum ceramic balls (TYPE A), and the other is thermal storage corundum ceramic balls (TYPE B).It widely used as catalyst bed support media in refining, petrochemical and gas applications, where low silica content or high alumina is required. With characteristics of high hardness, high density, high crush strength, excellent thermal properties, etc.
Technical Specification
Activated Alumina Ball is normally employed as catalyst bed support for chemical reaction towers in which foreigh matters should be strictly kept at minimum and the operating temperatures often above 500ºC.
The superior thermal properties combined with its high density and ability of withstanding 1500 ºC operating temperatures that make it a good choice for heat retention or equilibration media.It's high alumina content,low silica and high strength make it fit for high temperature and stream applications.
