Production of Smelter Grade Alumina (SGA) by Calcination
The first recorded use of rotary kilns for calcining aluminium hydroxide dates to 1935. Rotary kilns have been used for calcination of hydrate to Floury type SGA (mostly in Europe and Asia) or Sandy type SGA (mostly the Americas). In 1972 the largest 4.3 m dia. × 122 m rotary kiln was supplied with a capacity of 1400 tpd sandy alumina.
