Mechanistic modeling and simulation of grinding iron

The material used as the basis for the work was an iron ore pellet feed collected in Vale's pelletizing complex in Vitória (Espírito Santo state, Brazil). The specific gravity (ρ s) was measured as 5.1 g/cm 3 and the top size was 9.5 mm. Samples collected from batch and pilot-scale tests were initially homogenized, air-dried, and quartered. Material coarser than 2.36 mm was removed from the samples for the batch grinding
