Abstract

PURPOSE: To obtain activated alumina of high strength by rapidly dehydrating and drying alumina hydrate, indirectly cooling the resulting activated alumina with a cooling medium at once, and forming the cooled alumina into granules.
CONSTITUTION: Al(OH)3 fed from hopper 3 is dried with hot gas of ≥300°C generated from burner 1 in drying pipe 2, and the resulting activated alumina is sent to cyclone 4. Activated coarse alumina particles in cyclone 4 are introduced into screw 10, and activated alumina fine particles not captured by cyclone 4 are carried 6 to bag filter 7 and introduced into screw 9. The activated alumina formed in the above-mentioned process is then introduced into cooling tower 11 with screw 9, 10 and rapidly cooled with cooling pipes stretched in tower 11. The rapidly cooled activated alumina is discharged 14 out of tower 11, pulverized in the next process, and formed into an alumina carrier.
