Figure 1 shows a simplified diagram of a sinter plant. Materials enter the sinter plant from storage bins. They are mixed in the correct proportions using weigh hoppers, one per storage bin, except for the return fines for which an impact meter is used instead. Weighing is continuous, as is the whole sintering process.

Pelletization process. A pelletizing plant normally has four process steps namely (i) receipt of raw materials, (ii) pretreatment, (iii) balling, and (iv) induration and cooling. ... balls are charged at the top and descend through the furnace at a rate of 25 to 40 mm per minute countercurrent to the flow of hot gases. About 25 % of the total ...
In the first part of this chapter, the sinter process is described, the resulting emissions are characterized and primary measures to reduce the off-gas volume and the emission of …
Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be ...
Sintering is an agglomeration process of fine mineral particles into a porous mass by incipient fusion caused by heat produced by combustion within the mass itself.
Steel making using the integrated blast furnace (BF) process route is still the dominant steel production method covering 70% of worldwide steel production and iron ore sintering is one of the most important iron sources within this process, which represent 70–80% of charged iron-bearing materials into modern BF [].Inside this route, sinter plants offer …
