Compression Testing of Green and Dry Iron Ore Pellets

The load diameters, fracture diameters, and compressive strengths for the 2.01 lb/min and 3.67 lb/min rates are not significantly different at the 95% level, but these parameters are significantly different for the 3.67 lb/min and 4.20 lb/min rates. Some of the increase in fracture load is caused by the immediate failure of the weaker pellets.
