Inert Alumina Ceramic Balls

Product Description

inert alumina ceramic balls as catalyst bed support media. inert alumina ceramic balls has low water absorption, lower ratio of the moisture absorbing, high stronger resistance to high compressive strength and temperature strength. Inert alumina ball can increase the distributing spots of gas or liquid, also support and protect the activated catalyst from the rushing of the gas and liquid inside of the reactor. Inert alulmina ceramic balls can be widely used in petrochemical industry, chemical industry, fertilizer industry, natural gas industry and environment protection etc. inert ceramic balls’ alumina content could also be 17%,19%,25%,50%,65%,70%,95%,99% upon customer’s request .

Inert Alumina Ball’s specifications:

Aluminum Ceramic Balls are available in different diameter from 2mm to 75mm per customer request.
