12/28/2015· In Sweden and Germany, use of major amounts of fines in the sinter mix led to limited productivity, and thus brought about the first phase of the development in the pelletizing process. The first patent on pelletizing was granted to AG Andersson of Sweden in 1912 (Patent number 35124) and in 1913 to CA Brackelsberg in Germany.

Typical sinter mix consisted of 1-10mm Mn-ore fines, <6mm coke fines, return sinter fines and flux additives. Materials are pelletised in a rotating drum where moisture additions are made. The raw sinter mix is then layered on the hearth layer to a total depth of about 500mm. Ignition of the coke in the mix is by horizontal burners.

With a view to examine the cold handling property of produced sinter, the shatter test was conducted as per standard: IS9963-1981-2003 by dropping 2 kg of agglomerate sample of size range, +10 to –40 mm from the height of 2.0 m for four times over a 10 mm thick mild steel (MS) plate.

The cake was crushed to the desired size and the composite mass obtained was termed as Pellet-Sinter Composite Agglomerate (P-SCA). The sinter was characterized chemically, physically and physico-chemically. Kinds of sinter made and their details are presented in Table 6.

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 furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals.

4.2.2 Sinter. Low-temperature (< 1300 °C) iron ore sinter is an agglomerate of unmelted and partially melted nuclei particles (+ 1 mm) and a matrix bonding phase produced from the melting of fine ore (− 1 mm) and flux particles, with the majority of melt formation occurring in the granule adhering fines layer. The majority of nuclei are ...

LP series features low friction design for difficult, heat-sensitive, sticky or wet agglomerate. Granulators, pulverizers and shredders As filler particles and the resulting agglomerates become smaller in size, dispersion measurement becomes more challenging (ref.

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 furnace.The 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 chemical ...

agglomerate into a porous compact heterogeneous lumpy mass called SINTER by incipient fusion caused by the heat produced during the combustion of the solid fuel within the moving bed of loosely particles. The coke at the top of the blend is ignited by gas burners, that can be fueled by coke oven gas, blast furnace gas, or natural gas.

1. Introduction. The mechanical behavior of agglomerates is a subject of interest in industry because it is critical to the production and performance of agglomerated matter in a wide range of unit operations and applications such as granulation, drying, compaction, dispersion, drying, transport, and storage.

catalysts, however, is that under reaction temperatures and pressures, the clusters tend to sinter, or agglomerate, leading to a dramatic decrease in activity. In an attempt to make these highly active Au catalysts more stable, mixed-oxide supports have been developed by substituting Ti atoms for Si in a silica thin film network.

Sinter plants agglomerate iron ore fine particles (dust), with other fine materials at high temperatures, to create a product that can be used in a blast furnace. The final product, so called "sinter", is then used to convert iron into steel. The sinter is a small, irregular nodule of …

5/11/2020· Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.

11/25/2018· Theory and Practice of Sintering of Iron ore 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 particular form of ...

Agglomeration, the sticking of particles to one another or to solid surfaces, is a natural phenomenon. For powders and bulk solids, agglomeration can be unwanted, resulting in uncontrolled buildup, caking, bridging, or lumping. It can also be a beneficial process, utilizing the controlled enlargement of particles to improve powder properties and obtain high-quality products.
