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.
The Grate, the Kiln and the Cooler. The object of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed.
