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 optimize solids concentration in ball milling of an iron ore ...

Sample 3 is a high LOI (%) bearing iron ore pellet feed material, where % kaolinite and % 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.
