Iron ore fines, coke breeze, limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at the Sinter Plant, which forms 7080% of iron bearing charge in the Blast Furnace. The vertical speed of sintering depends on the suction that is created under the grate.
Iron ore sintering involves the movement of a flame front down a particulate bed, and a series of phys icochemical reactions over a large temperature range. In the literature simple and more ...
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 dedusting system ESP) and plant waste are mixed in proportion (by weight) in a rotary drum, often called mixing and nodulizing drum.
The main tlux added to iron ore sinters and iron ore pellets are limestone and dolomite which ... In this investigation iron ore sinter having basicities of and. The Blast Furnace The Potteries The purpose of a blast furnace is to chemically reduce and physically convert iron ... where iron ore, coke and limestone are dumped into the top, and preheated ...
The unit consumes Coke, Coal for MBF, Iron ore fines, limestone, dolomite, quartzite and coke breeze for Sinter Plant, Iron ore fines, Limestone, coke breeze, bentonite for Pellet Plant and coking coal for coke oven as raw materials. Address : Bhorandiha, Udnabad, Giridih (Jharkhand) Established : 2009. Facilities Products. Sinter Plant
Small piles were prepared by layering the iron ore fines, coke breeze, limestone, dolomite, burnt lime and return fines and HMDS Slag on weight basis. Figure 5 Disposed LD HMDS slag at slag yard All these constituents were thoroughly mixed. After ensuring proper mixing of these raw materials, the base was transferred to the granulation drum.
The iron is usually ground to a very fine level and mixed with limestone or dolomite as a fluxing agent and bentonite or organic binders as a binding agent. If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets.

Iron ore mining methods vary by the type of ore being mined. . The first is avoidance; don't use ore or a lime source with a high aluminium content. calcined lime addition in iron ore sintering – Caiman Mining. Effect of burnt lime addition on sintering of iron ore fines . Sharma, Abhishek and Rai, Nandani (2010) Effect of burnt lime addition on sintering of iron ore fines.
BF include iron oxide, metallurgical coke, sintered ore, manganese ore, and dolomite (Buschow, 2001, pp. 4293–4296). Development of a method for evaluating raw materials for use in iron ore sinter in terms of lime assimilation by W. Ferreira*, R. Cromarty*, and J. de Villiers*
sinter chemistry and the base mix proportion for the pot tests are shown in Table 3 and Table 4 respectively. Small piles were prepared by layering the iron ore fines, coke breeze, limestone, dolomite, burnt lime and return fines and HMDS Slag on weight basis (Table 4). All these constituents were thoroughly mixed.
Modelling fuel combustion in iron ore sintering . Modelling fuel combustion in iron ore sintering of a typical iron ore sintering plant. The major processes of granulation, bed ignition, sintering on the strand, sinter crushing and waste gas processing are shown. The higher FFS has the potential benefit of increasing sinter plant productivity.
Sinter is a hard, strong and porous mass, produced by the incipient fusion of iron bearing materials, limestone, dolomite and coke fines. The heat is generated within the mass itself by burning coke. With the use of sinter in mini blast furnace, fuel consumption rate can be significantly brought down and simultaneously improvements in productivity and hot metal quality can be achieved.
Jan 11, 2013· A blast furnace charge consists of coke, ore or sinter, and limestone. These materials must be in lumps of a certain size (4060 mm). Larger lumps prolong the process of reduction and fluxing. Smaller lumps block the fluegas passages and prevent a uniform descent of melting materials in the furnace. 2. IRON ORES: Ore is a metal bearing mineral.
Reduction in coke rate in blast furnaces; SINTERING PROCESS A Sinter Plant typically comprise the following subunits as shown below. The raw materials used are as follows Iron ore fines (10 mm), coke breeze (3 mm), Lime stone dolomite fines (3mm) and other metallurgical wastes.
Iron ore sintering ScienceDirect. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described and the key steps of the sintering process, namely, granulation and thermal densification, are identified.
