8. Calcination. The filter cake is fed into calciners where they are roasted at temperatures of up to 1100°C to drive off free moisture and chemically-connected water, producing alumina solids. There are different calcination technologies in use, including gas suspension calciners, fluidised bed calciners and rotary kilns.
In a wet-process or preheater system without a pre-calciner, most of the calcination takes place in the rotary kiln within a moving mass of feed. This situation is not ideal for calcination because heat transfer has to take place through a large mass of material and CO 2 has to escape outwards as heat moves inwards.
