Granulation an overview ScienceDirect Topics

L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.2.1.3 Chemical characteristics of iron ore. Granulation is generally considered to be a physical process involving the physical interactions of particles mainly through capillary forces. The influence of ore chemical characteristics on granulation is therefore largely neglected in the literature.
