Sinter plant
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 alSintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, (PDF) Iron Ore Sintering: Process ResearchGate

Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), The Sintering Process of Iron Ore Fines IspatGuru

Sinter Mix an overview ScienceDirect Topics
1.1.3.2.1.2 Iron-Bearing Materials. Ore fines and iron concentrates make the main part of the sinter mix.The grain size of ore fines and concentrates is typically 0–8 and 0–3 mm, respectively. Grains smaller than 0.1 mm are not desired because they reduce the gas permeability of the bed and thus decrease the sintering efficiency.Recycled materials, and sulphur to produce low –Si, low-S iron. 7.

Iron ore granulation for sinter production: Developments,
The kinetics of iron ore granules growth is also an important issue of greater engineering concern 42-44). In the actual iron ore granulation drum, the particle growth is often dependent on one or several modes of conversion between mechanisms. Population balance model (PBM), proposed more than thirty years ago, was first used in laboratory-Prior to dispatch of sinter to the blast furnace for hot metal production, the sinter product from the sinter cooler is screened to remove smaller/finer particles. The undersize so generated is called internal return fines, which are generally recirculated into the sintering machine. A very high level of internal return fines generation limits the use Prediction and Optimization of Internal Return Fines Generation in Iron

Virtual Sinter ® : Digital Twin for Integrated Sinter Plants
Sinter Plants, that produce iron ore sinter, are important units in an integrated steel plant. They face several operational challenges due to frequent changes in input raw materials, the inability to instrument key equipment in the plant, and the absence of real-time sinter quality measurement. To address these challenges, Virtual Sinter®, a In this study, a sintering test of high-alumina limonite from Indonesia, matched with an appropriate magnetite concentration, is performed. The sintering yield and quality index are effectively improved by optimizing the ore matching and regulating the basicity. For the optimal coke dosage of 5.8% and basicity of 1.8, the tumbling index of Characteristics and Sintering Mechanisms of Iron Ores with a High
