Sinter Plant - an overview | ScienceDirect Topics

The process to harden pellets by heating them up to the sintering temperature is called induration. There are three induration processes: Grate-Kiln, Straight Grate, and Vertical Shaft furnace, of which the first two are dominating whereas the shaft furnace is retreating. Figure 1.1.11 illustrates a typical pellet firing process [22].
