feed mix for iron ore sintering

Sinter plant - Wikipedia

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

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. The raw materials are sometimes mixed with water to provide a cohesive matrix, and then placed on a continuous, travelling grate called the sinter

Effect of Sinter Mix Composition and Additives on the ...

01/11/1955  Effect of variations in sinter feed composition on sinter strength, bulk density, re-ducibility, chemical composition, and microstructure were determined by sintering experimental samples on a production sintering machine. Increasing amounts of roll scale, ore fines, return fines, and blast furnace slag were most beneficial to feed permeability, sinter bulk density, and strength.

Theory and Practice of Sintering of Iron ore – IspatGuru

25/11/2018  The sinter mix which forms the sinter bed consists mainly of iron ore, coke breeze, fluxes and return fines. The behaviour of the sinter mix during sintering and the quality of sinter is dependent largely on the chemical, granulometric, and mineralogical composition of the iron ore. The ore characteristics impact the sintering behaviour and hence it is an important aspect in sinter production ...

The Sintering Process of Iron Ore Fines – IspatGuru

09/03/2013  The sintering process is used to agglomerate a mix of iron ores (blend), return fines, fluxes and coke, with a particle size of less than 10 mm, so that the resulting sinter, with a screened size of 10 mm to 30 mm, can withstand pressure and temperature conditions in the blast furnace. Principle of sintering. Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by

Kinetics of iron ore sinter feed granulation - ScienceDirect

01/08/1990  INTRODUCTION Granulation of sinter feed occurs prior to the sintering process. Fine iron ore (-8 mm) is mixed with coke, fluxes and screened sinter fines. The mix is granulated in a rotating drum after addition of water. The granules are then sintered as a packed bed on a moving strand. The size distribution of the granulated 0032-5910/90/$3.50 product strongly affects the on-strand ...
