The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized approach subject to many variations. In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

As highgrade iron ore deposits become more limited, it is necessary to upgrade lower quality iron ore resources through concentration. The ground iron ore must be pelletized prior to feeding into a blast furnace or DRI plant. Our pelletizing equipment is designed to produce pellets of highest quality at the lowest cost.

Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.

The dominant process adopted to produce iron ore pellets in China is the gratekiln process [1012]. The preheated pellets roll in the rotary kiln and can be sintered uniformly; therefore, it is known that the gratekiln method yields a superior and more consistent pellet quality compared with the straightgrate process [13].

For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during the smelting. The configuration of iron ore powder in a blast furnace is more tightlypacked and restricts the air flow.
