Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (limestone) fines. In addition to base mix, coke fines, flux fines, sinter fines, iron dust (collected from plant de-dusting system & ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum. Calcined lime is used as binder of the mixed material along with water (all in particular proportion by weight) to form feed-sinter of about 5 to 7 mm in size. This sinter globules are f
Jul 07, 2017· Limestone is normally added during ironmaking for obtaining either neutral or slight basic BF slag. Addition of limestone through sinter is more preferred route since CO2 of limestone is driven out during the sintering process. In case of sintering, limestone is crushed to -3 mm (in the range of 85 % to 90 %) in hammer crushers before mixing it in the sinter mix.
Sinter improves blast furnace operations by combining the blast furnace flux into the sinter rather than charging it separately to the top of the furnace. Iron ore fines, limestone and dolomite form agglomerated sinter through low temperature ovens.
Jun 15, 2010· Iron ore fluxed sinter is the main ferrous burden of Jindal south west steel limited (JSWSL) blast furnaces. In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace. The raw material grain size affects the sinter process
At the plant these are initially stored with the help of a stacker in piles. Different reclaimer types are used to reclaim the materials from the piles and discharge to different conveyors for delivering the materials to the main plant. 4. Sinter plant: Prior to sending iron ore it is sintered at the sintering plant along with limestone and some coke. Here fines are agglomerated into lumps.
Influence of limestone particle size on iron ore sinter . Iron ore fluxed sinter is the main ferrous burden of Jindal south west steel limited (JSWSL) blast furnac In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore
Limestone and dolomite flux and their use in iron and steel plant. Limestone is a naturally occurring mineral. The term limestone is applied to any calcareous sedimentary rock consisting essentially of carbonates. The ore is widely available geographically all over the world. Earth’s crust contains more than 4 % of calcium carbonate.
Jun 11, 2019· 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 suitable size for charging into the blast furnace.
The flexibility of the sintering process permits conversion of a variety of materials, including natural fine iron ores, ore fines from screening operations, captured dusts, ore concentrates, return fines not suitable for downstream processing, other iron-bearing materials of small particle size (sludges, mill scale etc.), and wastes and screenings of lime, limestone and dolomite into a clinker like agglomerate that
Sinter improves blast furnace operations by combining the blast furnace flux into the sinter rather than charging it separately to the top of the furnace. Iron ore fines, limestone and dolomite form agglomerated sinter through low temperature ovens.
Our quality limestone and burnt products with optimized size distribution impacts the environmental footprint of the mill by improving the sinter productivity and reducing overall energy cost and emissions. IMPACT YOUR PROFITABILITY Read case studies Read white papers Profitability Solutions: Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel
Jun 15, 2010· Iron ore fluxed sinter is the main ferrous burden of Jindal south west steel limited (JSWSL) blast furnaces. In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace.
Our chemical grade limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Our limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.
Our milled limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Our milled limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.

Modeling Sintering Process of Iron Ore Jose Adilson de Castro Graduate Program on Metallurgical Engineering -Federal Fluminense University Brazil 1. Introduction In this chapter, a methodology for simulating th e sintering process of iron ore is presented. In order to study the process parameters and inner phenomena, a mathematical model
Nov 25, 2018· Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a
FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION 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
