Daswell Lime Calcination Plant

So the process can be a little complex than the lime production line with vertical lime kiln. Firstly, the sifted limestone of required sizes is transferred to the silo in pre-heater by belt conveyor. Then in the pre-heater, the limestone is pre-heated to about 900 degrees, through which about 30%-40% of limestone will decompose.

Calcination of Limestone – IspatGuru

2013-5-2 · Some limestone, due to its crystalline structure, disintegrates during the calcination process. This type of limestone is not useful for calcining. There is some other limestone whose behaviour is the opposite. This type of limestone become so dense during calcination that it prevents the escape of CO2 and become non porous.
