iron ore sinter feed size distribution

Prediction of the granule size distribution of iron ore

Jul 01, 2016 In the case of iron ore granulation the development of the population balance is complex because of the ambiguous behaviour of intermediate particles,,,,,,,, . The particle size distribution of sinter feed is wide and is categorized as nuclei (coarse

Prediction of the granule size distribution of iron ore

Prediction of the granule size distribution of iron ore sinter feeds that contain concentrate and micropellets. Concentrate and micropellets in iron sinter mixtures decrease the mean granule size. and micropellets to a sinter mix will significantly affect the particle size distribution of the granules in the sinter feed.
