Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing. process since the beginning of pellet production in the 1950s. Bentonite promotes the forma-. tion ofSample 3 is a high LOI (9.19%) bearing iron ore pellet feed material, where 4.17% kaolinite and 81.47% goethite are present. As goethite is in fragile nature, the surface area is more after grinding in the ball mill for sample preparation. The moisture content in the green pellet increases with the increase of goethite due to its more surface area.Mineralogical investigation on preheating studies of high LOI iron ore

Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to HPS can be treated as an environmentally sustainable process as we can utilize iron ore fines and consume less coke, which is the need of the hour.
