Effect of Application of Compressive and Shear Force on Iron Ore Pellet …
Iron ore pelletizing using compressive and shear action on wet mixture feed has been studied. The physical properties, namely, moisture content, drop strength, green compressive strength (GCS), dry compressive strength (DCS), porosity, and cold crushing strength (CCS), have been studied. Pelletizing tests were carried out on four different …
Iron Ore Pellets – IspatGuru
01- 21194713. The typical specification for iron ore pellets is given in Table 2 below. Several pellet producers screen their pellets to remove fines prior to loading on board vessels or railway trains for delivery to the customers. The resultant screened off fines are known as pellet fines (also as pellet screenings or pellet chips).
Iron ore
Pellet Feed (<0.150mm): The very fine iron ore product is obtained after the flotation process. In order to be used in the steelmaking process, it should be pelletized. At smaller percentages, it can also be blended into sinter feed and used at sintering units. The iron content of the CSN Mining pellet feed usually exceeds 66%.
