Short introduction :
 Inert balls are to increase the distribution spots of gas or 
liquid , widely utilized as the covering or supporting materials of the catalyst in the reactors 
and the packing in the column in such varies areas as petroleum , chemical industry ,
chemical fertilizer and support or protect the active catalyst , which especially 
have the comparatively lower mechanical strength
