Compression Testing of Green and Dry Iron Ore Pellets

21/08/2019 · The load diameters, fracture diameters, and compressive strengths for the lb/min and lb/min rates are not significantly different at the 95% level, but these parameters are significantly different for the lb/min and lb/min rates. Some of the increase in fracture load is caused by the immediate failure of the weaker pellets.
