straight grate pellet induration

Iron Ore Pellets Induration Solutions Metal 7

Iron Ore Pellets Induration Solutions; The straight travelling grate consists of a horizontal furnace divided in zones through which a grate moves slowly through each zone,, exposing the pellet bed to a progressive increase in temperature. The temperature is controlled in each zone to maintain the appropriate firing curve.

In the cooling zone, pellets are brought down to a suitable temperature for downstream material handling equipment. The gases from the cooling zone are recycled to the indurating area and the pre-heat and drying zone, resulting in the straight grate being the most energy efficient system for producing indurated pellets.

Dynamic simulation of pellet induration process in

Dec 05, 2008· Fig. 1 depicts schematic of a typical straight-grate induration system. The grate bars fixed on a moving strand are first covered with a layer of burnt pellet, known as hearth-layer. The green pellets containing 7 to 9 wt.% free moisture and 10 to 14 mm in size are then fed onto this layer and travel together with the sub-layer through several thermal zones of the furnace.
