Physical properties of initial iron ore pellets

Physical characteristics of wet pellets have been considered. It has been shown that multicomponent wet pellet is three-phase system which is characterized by certain relation between solid, liquid, and gaseous components. Mathematical models of physical properties of components have been developed. Thickness of film of absorbed water can be determined with the use of the model. Physical properties of initial industrial fluxed pellets have been presented. Calculations have shown that diameter and porosity of wet pellets are larger that those of dry pellets. Value of optimal moisture content can be determined.
