Abstract
PURPOSE: To obtain alumina granules having high strength and superior attrition resistance by adding a binder to activated alumina powder ≥70wt% of which has been specified in particle size and average particle size, and granulating the mixture.
CONSTITUTION: Alumina hydrate obtd. by the Bayer process or other process is partially dehydrated to prepare activated alumina powder having preferably 5W 20% residual water content. At this time, the powder is adjusted so that ≥70wt% of the powder has ≤5μ particle size and ≤3μ average particle size. A binder such as crystal cellulose is added to the powder and mixed. After adding water the mixture is formed into spheres, etc. of a desired diameter, aged in satd. steam, and activated by calcination to obtain activated alumina granules having superior warming effect, high strength and superior attrition resistance.
