    Jan 01, 2012· In Grate-Kiln process, green pellets are fed on oil or gas-fired endless Straight Grate machine where they are dried and preheated. The preheated pellets are then fed to a rotary kiln where their temperature is raised in oxidizing atmosphere to 1290–1400 °C. In induration, ore grains are sintered together with oxidation and slag-forming bonds.

  • WHAT IS AN INDURATING FURNACE

    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.
