Inert Ceramic Ball-70
Al2O3 content: 70%~75%
Packing density: 1500~1600kg/m3
National standard: HG/T 3683.1-2014
Loading capacity: 25 tons max by 20”GP & 40”GP.
Application: Used as the support media to protect active catalyst in the reactor.
Description：
Inert ceramic ball-70 is also called 70% alumina ball or medium alumina ball. It has very excellent thermal properties, with high-temeprature resistance 1450 ℃, also as a good choice for heat retention. It’s suitable in olefin processes, such as ethylene dryers, where’s the polymerization problem.
