In the Kiln, pellets are brought up to final indurating temps. Rotation of kiln exposes entire pellet bed to heat radiating from the burner resulting in uniform pellet quality. The kiln burner utilizes cooler off gas to heat material bed to nominal of 1200-1340 °C completing the slag bonding and mineral bridging to form pellets.

In an Indurating Furnace, the pellets are loaded on to a travelling grate to a depth of approximately 3060cm where they are preheated (typically to 800- 9000C), before entering a - higher temperature stage (around 1,200-1,3500C) which in some designs is a continuation of the travelling grate, and in others take the form of a rotary kiln.
