calcination after sintering of iron ore

In addition to the binding property, burnt lime also reduces the coke breeze rate due to reduced calcination of limestone during the sintering process.the iron ore deposits have exhibited an increasingly complex mineralogical composition nowadays with the rapid consumption of iron ore resource around the world 23. statistically, the

Iron processing - Ores | Britannica

Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is

What Is Iron Ore Sintering? (with pictures

Depending on the specific machine and iron ore sintering process used, substances such as coke breeze and burnt limestone are used to ignite and heat the iron ore particles until the particles congeal. Once congealed into an agglomerate, the ore is again crushed.

Effects of Particle Size of Coke on Iron Ore Sintering Process

The results showed that the fine coke breeze burned quickly, but high ratio of fine particle in coke breeze was not beneficial for the improvement of the sinter quality. The low permeability of the front section of the sintering machine caused the low combustion efficiency of coke breeze which could

The Relationship Between Mining and Sintering

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 suitable size for charging into the blast furnace.

CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in productivity and saving in coke rate to the blast furnace. The technology of sinter making

size distribution of iron ore fines must be 10 to 0.15 mm and mean size of the ore fines shall be 3 to 5 mm. Coke Breeze: In integrated steel plants, coke breeze is a by-product of coke oven battery which is used as fuel for sintering process. The coke crushing index should be 90% (-3.15mm) and the -0.25 mm percentage should be within 25%.
