Binding mechanisms in wet iron ore green pellets with a ...

2006-11-13 · From the balling of iron ore concentrates, it is known that as the raw material becomes finer, the moisture content needs to be increased to preserve the ballability of the pellet feed. Therefore, if the moisture content for the finest material was too low, the consolidation rate would have changed due to different plasticity in the agglomerates.
