Iron Ore Pellet
Iron ore pellets are a type of small-sized iron ore balls which are spherical and made of iron ore fines. They are manufactured by mixing beneficiated iron ore fines or natural iron ore fines with additives, then being processed into green pellets, and finally indurating at a high temperature. Iron ore pellets are the indispensable material used in steel making process. It is the basis of the steel industry, which features high iron grade, uniform particle size, good reduction performance, high mechanical strength, and long storage time.
Highlights of iron ore pellet in the steel industry
Global Iron Ore Pellet Market Continues to Grow
The iron ore pellet market is expected to achieve stable growth from 2021 to 2028. According to the analysis of Data Bridge Market Research, the market is growing at a CAGR of 3.6%.
Global Iron Ore Pelletizing Plants Construction Demand
Regarding iron ore pellets production and consumption, the Asia Pacific region is dominant. This is due to China’s huge steel manufacturing base. In China, the massive consumption of iron ore pellets by the steel industry makes the iron ore pellet production demand increasing rapidly. Because of the increasing demand for steel in the energy-intensive industry, United States has a dominant position in the North American iron ore pellet production market. As for the Middle East and Africa, iron ore pellet consumption in the two regions is expected to grow steadily in the coming years as the economic diversification plan initiated by the government aims to reduce dependence on oil and gas energy. It is expected to push forward steel production and manufacturing industry in the coming years.
Why We Need Iron Ore Pelletizing Plant?
With the decrease of high-grade iron ore, we gradually pay attention to its recycling and meanwhile increase the utilization of low-grade iron ore. Iron ore pelletizing plants play an important role in these two aspects.
For low-grade iron ore, they should be beneficiated to improve the iron content. We usually grind up iron ore after mining and remove the useless part (tailings). Therefore, most of the iron ore that is sent into the steel plants has a fine particle size. Iron-making blast furnace requires high air permeability during operating so the iron ore fines should be processed into iron ore pellets in the iron ore pelletizing plant in advance.
During the processing of high-grade iron ores which don’t need beneficiation, many ore fines are generated which are usually regarded as waste. In iron ore pelletizing plants, these iron ore fines can be recycled and pelletized for steel making instead of being disposed of.
Because of its advanced production technology and automatic production process, iron ore pelletizing plants meet the needs of various steel enterprises. The iron ore pellets produced by it feature high iron content and uniform specifications, which effectively improve the production efficiency of the steelmaking plant, reduce environmental pollution, and increase the benefits of the enterprise.

Iron Ore Pelletizing Process
The iron ore pellet production process mainly includes four steps: raw material preparation, mixing, balling, and indurating.
Raw Material Preparation
Raw materials for iron ore pellet production include iron ore concentrate, binder (bentonite), fluxing agent (limestone or dolomite), and other additives. In this process, all these materials need to be ground to a certain fineness and then stored separately in silos.
After preparation, raw materials are batched under the control of a batching system. Then they are fed into a mixer for adequate mixing.
Pelletizing disc is the most commonly used balling equipment in iron ore pelletizing plants. Materials on pelletizing disc are mixed with an appropriate amount of water to be processed into green pellets. Once pellets have reached the desired size, they leave the pelletizing disc and proceed to the next step. But if the green pellets are oversized or undersized, they will be screened out and sent back to the mixer or balling area.
In the induration process, green pellets are thermal hardened. This process is usually carried out in a grate kiln. In the grate kiln, pellets are heated up to a temperature of about 800-900 °C in the preheating zone, then they finish the induration at roughly 1200-1350 °C. After that, all the iron pellets enter an annular cooler for cooling until reaching a normal temperature for further storage or transport.
