Introduction to Iron ore Pellets and Pelletizing processes. Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter ...

Coke is the best fuel for iron ore sintering. Size classification is a crucial factor. The best economy and efficiency is achieved with a coke particle size of less than 3 mm. Some studies have shown that the best coke size for sinter productivity and reducibility is between 0.25 mm and 3 mm. Another study has shown that although a coke size of ...

The size of iron ore affects the sintering properties. An increase in the size of iron ore promotes the productivity of sinter, but can reduce the tumbler strength slightly and save a little coke. The mineralogy of sinter can more easily be predicted from its chemical composition than its physical and chemical properties.

Iron Ore is the most important raw material needed to produce steel. However, it cannot be used directly in the blast furnace. That is why sinter is created that helps convert iron into steel. Rashmi Metaliks has its own Sinter Plant set up at 2007 to have complete control over the quality of materials used in the steel production process.
