  • Iron Ore Pellets and Pelletization Process IspatGuru

    11/26/2014· The addition of lime (CaO) to the iron ore fines slightly decreases the productivity of green pellets, but increases the drop resistance and the compressive strength of green pellets. Further the strength of the pellets is directly proportion with the shrinkage that takes place during firing of the pellets.

  • A Look at the Process of Pelletizing Iron Ore for Steel

    Iron ore must go through a lengthy pre-processing stage before it can be pelletized a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.

    Pelletization is a convenient way to manage the separation of incompatible drugs. Pellets offer reduced variation in gastric emptying rate and intestinal transit time. Pellets disperse freely in G.I.T. and invariably maximize drug absorption and also reduce peak plasma fluctuation 12. Pelletization solves the problem of taste masking.

    The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
