Abstract Taking the conventional magnetite concentrate used in the pellet shaft furnace as the reference object, the optimal parameters of conventional magnetite concentrate pellets were used as the test conditions for the hematite addition test, which included the pellet preparation parameters, preheating parameters, baking parameters etc. The pellet properties and compressive strength of two different kinds of iron concentrate with different ratio of iron ore concentrate were studied and compared with that of conventional magnetic concentrate. The analysis of the experimental results showed that the proportions of the two concentrates were reasonable. The mechanism analysis, the comparison of the drying speed of pellets under different temperatures and the study of the properties laid the basic data and theoretical analysis conditions for the later industrial production.
