Grate process is an important step in grate-kiln pellet production. However, as a relatively closed system, the process on grate is inaccessible to direct detection, therefore, it is hard to control. As a result, mathematical models of temperature distribution, moisture distribution and oxidation degree distribution in pellet bed, with good …

The local exergy destruction rate of grate, kiln, and cooler is 74.2%, 14.1%, and 7.7% respectively, indicating the grate is the most important exergy destruction resource. We also studied the effects of reference environment temperature on exergy efficiency in the GKC plant and its major components, and the thermodynamic data …

Induration (drying and hardening) of iron ore pellets is an energy-intensive feed preparation step for both the blast furnace and direct reduction routes to iron. It is commonly carried out by a 'grate/kiln' process. A mathematical model of the process is described, in which mechanistic models of the grate furnace, kiln, and cooler are linked to enable simulation …

Grate Kiln design allows for a lower bed depth compared to a straight grate, resulting in more uniform temperature profile, a lower pressure drop, and less power consumption. ... The Travelling Grate is where pellets are dried and then heated up to a temperature of about 800-900 deg C. The heat used to dry and preheat the pellets is typically ...

We are also on the verge of commissioning a 1.8MTPA Beneficiation Plant and a 0.1MTPA Steel Plant. Iron Ore Pellet : Arya Iron & Steel Company Pvt. Ltd.

The pellets at the bottom of the bed also undergo the greatest compressive forces due to the weight of the pellet bed and the pressure of the gases pushing the pellets against the grate plates. The compressive forces will compound if the bed begins to deform, as the voidage in the bed will decrease and the gas pressures will increase.
