The production of iron ore pellets, which is vital to the production of steel, is expected to be an important industry for many years to come. The pelletizing of iron Merchant DR-grade iron ore pellet demand may increase to 53 million mt in 2025 from about 38 million mt in 2020, and rise to 81 million mt in 2030, according to IIMA estimates. Around 28.5 million mt of estimated market-based DR pellet demand in 2030 is expected to come from new DR plants, mainly in Europe and the MENA region, at which DRI to underpin carbon-neutral steel; growth needed in pellet

Recycling and Reuse of Iron Ore Pellet Fines SpringerLink
During the process of iron ore pelletization and preparation of feed for DRI or reduction smelting processes, around 3% of pellet fines (less than 8 mm) are generated as undesired product in the existing pellet plants. Such pellet fines acquire more than 24 million tonnes generated all over the world. Recycling and reuse of these high gradeOur manufacturer has designed and supplied Grate Kiln for several pellet plants, playing a leading role in the industry of China.

Reduction of low grade iron ore pellet using palm kernel shell
The ores were consumed mainly by the local cement, iron and steel plants. The Malaysian Iron and Steel Federation (MISF) estimated that the country's steel consumption increased by about 24% to 8.2 million tonnes in 2010 [3], [5]. At present, Malaysia's steel industry imports its raw material in lump and pellet forms as the mills that utilize this process also have auxiliary operations in the form of coke and sinter/pellet plants. According to the American Iron and Steel Institute, coke is the most important raw material fed into the blast furnace (Valia, 2015). It is used to reduce iron ore to iron.

MIDREX NG provides greater raw material flexibility by allowing the use of DRI-grade pellets, blast furnace-grade pellets, and lump ores. Compared to blast furnace ironmaking, a standard MIDREX NG plant can reduce CO 2 emissions by more than 50% and has the flexibility to be converted from 100% natural gas to 100% hydrogen as the The quality requirements of pellet, such as physical, chemical and metallurgical specifications, depend on each ironmaking furnace and thoserequirements influence the operation ofthe iron ore pelletizing plant.

Process through Multiscale Process Modeling
Iron ore pellets are charged at the top, descend due to gravity, and encounter an upward counter-flow of gas. The reducing gas (CO and H 2, plus CH 4, CO 2, and H 2O, at about 950 °C) is injected peripherally at mid-height and exits at the top.
