Grate kiln systems liming

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. The Travelling Grate is where pellets are dried and then heated up to a temperature of about 800-900 deg C.

Iron Ore/Taconite HarbisonWalker International

In the ironmaking process, the blast furnace or direct-reduced iron (DRI) plant will typically use iron ore pellets, which are created when iron ore fines are agglomerated and heated using a rotary kiln. Many producers use a traveling grate and rotary kiln to heat the pellets to temperatures as high as 800°C to 900°C in the preheat zone and as high as 1200°C to 1300°C in the burning zone of the kiln.

This was followed by the grate-kiln and the traveling grate, which together account for more than 90 percent of world pellet output. In shaft furnaces the charge moves down by gravity and is heated by a counterflow of hot combustion gases, but the grate- kiln system combines a horizontal traveling grate with a rotating kiln and a cooler so that

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.

Iron processing Iron making Britannica

Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
