Fives | Clay calcination with FCB Flash Calciner
To avoid reddish color during calcination, iron oxides are reduced to the magnetite form by a reducing atmosphere maintained down to the stability temperature of the magnetite. Unlike conventional methods, our principle consists in dissociating the reduction phase from the calcination by performing it only during cooling, thus allowing:
