A study on plasticity and compression strength in wet iron ore

Feb 12, 2008 From everyday practical experience we know that raw materials with wider particle size distributions need to be balled with lower moisture content than raw materials with more narrow particle size distributions. Therefore, balling at constant plasticity would be needed for a meaningful comparison of the green pellet strength.

Oct 24, 2021 Green pellet formation carries critical importance since the success of later phases of drying, preheating, and induration depends on the shape, size, and strength of green pellets. The optimum size of the pellets (8–16 mm) is needed to maximize the heat and mass transfer among the bed of pellets by providing the proper bed permeability.
