At Narsingh Ispat Limited, we operate three state-of-the-art sinter plants, each with a capacity of 600 Metric Tons Per Day (MTPD). These plants are essential to our iron production process, as they agglomerate iron ore fines and other fine materials at high temperatures to create sinter—a porous, small, irregular nodule of iron mixed with small amounts of other minerals.
A typical flowsheet of sinter process is shown in Figure 2. The product is a partially fused porous agglomerate, which is crushed and large lump material is fed to the blast furnace. Fine sinter material is recycled or returned to the sinter feed to act as a support for fresh feed. ... Lead sinter plant trials have been carried out at the ...

A Sinter plant in a steel plant is the final operation in a series of measures to prepare iron ore for blast furnace smelting.A sinter plant is an enterprise with a complicated technological process for producing the final product – agglomerate or sinter.. Agglomeration is a process of sintering fine ores and concentrates by fuel combustion in a layer of sintered material.
1. Raw Material Preparation: The first step is to create or acquire the powdered metal needed for sintering. The powders are often produced through atomization or chemical reduction. 2. Compaction: The powder is placed into a die or mold and compacted using high pressure to create a green part. This compacted part is fragile and requires further processing …
The sintering process is a highly energy-intensive and vast material-consuming process unit in hot metal production. Iron ore sintering depends on the raw mixture, sinter plant geometry, and ...
Optimus Sinter has a thermodynamic model at its core. This was developed using Outotec's unparalleled process expertise, years of experience in designing, delivering and commissioning of hundreds of sinter plants all over the world, as well as a strong know-how of process modelling in a variety of different metallurgical processes ...
Nowadays, the Dwight–Lloyd sintering machine is widely used in the sintering plant at home and abroad. ... In the sintering process, the quality of the sinter ore is closely related to some key state parameters such as BTP, bed permeability state, and ignition temperature. BTP, as an important state parameter, represents the position where ...
Our sinter plants have one ESP to filter the process gas and one ESP for de-dusting each. The filtered gas joins a common stack (excepting one sinter plant, without a bag filter). A sinter plant has maximized emission reduction of sintering (MEROS) and waste gas recycling (WGR) and another one high-temperature bag filter (HTBF).
Sinter Plant • In order to conserve these, otherwise waste material, they are compacted together and made into lumps by a process known as sintering. • Sintering is defined as the agglomeration of the fine mineral particles into a compact lumpy mass by incipient fusion caused by the heat produced during the combustion of the solid fuel ...
