Inert Alumina Ceramic Ball roduct Features:
Inert Alumina Ceramic Balls are widely used in petroleum, chemical, fertilizer,
natural gas and environmental protection industries. As a catalyst reactor
coverage tower packing materials and support, the major role is to increase the
distribution of gas or liquid, support and protect the intensity of low strength
activity catalyst.
