Crushing Strength. Since the iron ore does not contain any lime at that time and is likely unable to contribute to additional strength, practically equal values of the core and coating are obtained during the testing of green crushing strength for a 1-mm coating layer (Fig. 4a). Due to the capillary action of damp iron ore fines in the coating ...
