Sinter plants process a mixture of iron ore fines, recycled ironmaking products, slag-forming agents and solid fuel (coke) with the finality of obtaining a product with the suitable ...

The EFA process is installed at the end of the sinter plant process. It essentially consists of an entrained flow absorber and a bag-type filter. Using this equipment, from the sinter plant off-gas, dust, sulphur oxides, hydrochloric, hydrofluoric acids, dioxins and furans are captured. The absorber operates with hydrated lime …

Virtual Sinter ® is a digital twin of the sinter plant that receives real-time process and raw material data from plant data sources, simulates all the unit operations in the sinter plant in real time, soft-senses process and product quality parameters such as granule size distribution or sinter bed temperatures that are difficult or ...

The sinter plant model developed in gPROMS ModelBuilder® (6.0.4, Process Systems Enterprise limited, December 2019) characterizes main process effects based on three sub-models combining physio-chemical correlations with empirical correlations to minimize parametization of the model for calculation of mass and energy …

The ingredients – iron ore, coke and limestone fines – are carefully stacked and blended, then passed under an ignition hood at the sinter plant. This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnaces.

Sinter Plant Raj Kumar Goel, Managing Director, Vankam Vasu, DGM SLR Metaliks Limited, Email : [email protected] ... After completion of the sintering process, sinter cake will be crushed and screened after discharge from the machine. Sinter having size > 5 mm will go to the cooler and then

According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue …

Automated optical image analysis of natural and sintered iron ore. E. Donskoi, ... J.R. Manuel, in Iron Ore, 2015 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 …
