Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter as well as iron ore lumps. High porosity also helps in better metallization in DRI production. Pellets have a uniform size generally in a range of 8 mm -16 mm. Pellets have spherical shape and open pores which give them good bed permeability.
