Nov 13, 2006 This way, the deformation values are independent of the green pellet strength. 1 daN was chosen for the calculation of plastic deformation because it is generally known that wet iron ore green pellets must withstand this pressure in order for the pelletizing process to operate economically.Straight Grate iron ore pelletizing system Principles of operation • In this process, the wet pellets are dried, preheated, indurated, and cooled on a continuous moving grate without intermediate transfers. •The process air introduced for pellet cooling is circulated from the cooling zone of the grate in a multi pass manner to the other process.
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process.Pelletization process by Kshirod. 1.

The iron ore pelletizing process consists of three main steps 1. Pelletizing feed preparation and mixing the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process.Pellet Plant Process Raw material iron ore fines are fed to Iron ore grinding system (IOGS – 160 t h) for grinding the ore to 85 200 mesh. We use the wet grinding process for this.
Outotec's traveling grate pelletizing plant is the industry's leading induration technology for iron ore pellet production for a wide range of plant capacities. Based on over 60 years' experience and world class R D, our process produces uniform pellets and ensures high performance and quality, with low investment and operating costs, as well.The most commonly employed agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets). Figure 1 Iron pellets . The pelletizing process is a process which contains numerous sub processes, or process segments.
The company’s Mangalore units of Pellet Plant and BFUs are running with the outsourced hematite iron ore to convert into iron oxide pellets. Company’s pioneering R D programs proved fruitful in switching over the system designed for conversion of magnetite ore to that of hematite ore into iron oxide pellets under wet grinding process with.The location of a pelletizing plant affects the method of receiving raw materials such as iron ore, additives and binders. 2.2.1 Pre treatment process of Iron Ore Fines In the pre treatment process, iron ore fines are ground into finer size, suitable for green ball formation. Dry or wet grinding process is adopted for grinding the iron ore fines.
CPT is based on proven straight grate induration process • Simple and robust plant equipment The Challenge of making iron ore pellets Typical Flow Sheet of a Pelletizing Plant • Considerable benefits compared to conventional wet dedusting technologies • Fulfilling BAT requirements • Easily expandable by DeNO x MT ECO 0 10 20 30.Iron And Steel Production Environmental Protection Agency. diagram of the iron and steel industry in Figure 12.5 1.
