Coke breeze is the main heat source in sintering process. Its combustion yields enough amounts of heat which melts the sinter mix. One of the factors that significantly affect the course of coke breeze combustion is its grain size [1,2,3].It is known that fine-grained coke reduces permeability of the sinter mix and the use of coke …
Based on the particle size, iron ores are classified as iron ore fines (<10 mm) or iron ore lump (6.3–31.5 mm); iron ore fines are first processed in a sinter plant, while lump ores can be charged into the blast furnace (BF) directly. Iron ore lump is the lowest cost iron bearing material for the BF burden.
Sinter plants currently have to use many types of ores with different properties owing to the great demand for iron ores, which was driven by the massive growth in Chinese iron and steel industry. On the other hand, the development of iron ore mines is limited and the quality of iron ores is in a tendency of deterioration.

Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation.As shown in Figure 14.1, iron ore sintering is carried …
Iron ore sinter is an ordinarily utilized iron-bearing burden in BF iron-making unit. The sintering agglomeration procedure aims to form high strength sinter including granulating of the mixed materials, distributing the granulated materials and then igniting the fuels (coke or coal), sintering the iron-bearing materials by the combustion of fuel in a …
A sinter plant is used to agglomerate iron ore to produce sinter, a product that can be used in a blast furnace.[1] According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of …
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be …
Sintering of Iron Ore Fines Sintering is an agglomeration-technique for enlarging the iron ore particle size.
