Product Description

Zhongci 17 Ceramic Ball as Support Media

17%-19%Ordinary Ceramic Ball, is the most widely used support media in the world because of their excellent consistence and reliability.
Zhongci 17%-19% Ordinary Ceramic Ball, is manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.
 

Typical Application:  
Be mainly used in the petroleum, chemical industry, fertilizers, natural gas, environmental protection and other industries. It plays a role of supporting and compacting the packing of the tower.
