Binding Mechanisms In Wet Iron Ore Green Pellets With A

Nov 13, 2006 Iron ore green pellets show both plastic and elastic behaviour and the difference in significance between these two mechanisms should be recognised. Plastic deformation occurs due to the load of above-lying green pellets in a static bed of green pellets and leads to decreased bed permeability in the drying zones.
