Sinter plants agglomerate iron ore fines dust with other fine materials at high temperature, to create a product that can be used in a blast final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemicalGet Price
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming agents and solid fuel coke.
Primetals Technologies formerly known as Siemens VAI put a new sinter plant into operation in 2010 at the Taiwanese steelmaker Dragon Steel Co. The plant incorporates the latest sintering
030301 Sinter plants 73 030301 Sinter plants Process description By sintering, the pelletisation of finegrained, smeltable ores, iron ore in particular, to compact lumps by heating nearly to the melting or softening point is understood. Melting tendencies at the grain boundaries lead to a caking of the material.
Modeling Sintering Process of Iron Ore 25 Fig. 2. Thermal cycle of the materials in the sinter strand. Several attempts have been done to predict the final properties of the sinter product Water et al. 1989, Kasai et al. 1989, 1991. The most important parameters are reducibility,

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 turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.
The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, inplant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.
Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be
The problem involved in Manganese Ore Processing deals with the production of acceptable specification grades of manganese concentrates at a maximum recovery of the total manganese from ores having variable characteristics. The flowsheet provides for both gravity and flotation with a maximum recovery of the manganese values in a coarse size in the most economical manner by the use of jigs and
Increasing the basicity index CaOSiO2 between 0.1 and 3, chiefly through limestone admixture makes possible to reduce the thermal consumption of sintering and to improve the physical and chemical properties of the sinter. In the case of a plant using hematite ores, it seems interesting to produce an hyperbasic sinter and to complete the blast
CHAPTER11 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

Hot metal Iron hot metal produced at Scunthorpes iron works is further refined at the works steelmaking plant before being rolled at one of
sintering process, sinter cake will be crushed and screened after discharge from the machine. Sinter having size gt 5 mm will go to the cooler and then it will go to BF. Sinter with size lt 5 mm size fines will be recycled in the process. 4. Some of critical Equipments facilities in Sinter Plant are asunder Sl. No. Major equipments 1.
fluxes, Iron ore fines, SCFA, sinter, sinter plant. basic sinter, sintering machine, Understanding Sinter and Sinter Plant Operations Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself.
Outotec has built more than 400 iron ore sinter plants worldwide. This process, primarily used for iron ores, can also be used for sintering manganese and nickel ore fines. Our energy optimized version of the sintering EOS process reduces offgas volumes and the emission of hazardous pollutants, while simultaneously reducing fuel consumption.
Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but pelletizing plants are often located near the mining site. Some works have both pelletizing and sintering plants at the smelter sites. 184.108.40.206.2.2 Green Pellets

The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel called bonding agents in Japan such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron and steelmaking processes.
