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 %).

Introduction to Iron ore Pellets and Pelletizing processes ...

Blaine fineness is one of the most important parameters in pelletising. While the lower Blaine fineness does not provide sufficient strength to the both green pellet and indurated pellet, excessively high Blaine fineness causes problem in pellet making. Optimum Blaine fineness of iron ore in the range of 1700–2250 cm2/g is usually used for good quality pellet making.

Iron Range - Wikipedia

The air permeability specific surface of a powder material is a single-parameter measurement of the fineness of the powder. The specific surface is derived from the resistance to flow of air (or some other gas) through a porous bed of the powder. The SI units are m 2 ·kg −1 ("mass specific surface") or m 2 ·m −3 ("volume specific surface").
