More specifically, iron ore powder, flux such as limestone, fuel such as coke powder and return ore, etc. are mixed according to a specific proportion, and a proper amount of water is added, and the mixture is rolled and kneaded in a mixer such as a cylinder mixer, so that the materials form particles (also called 'pellets' or 'pellets') with uniform granularity, and the air permeability of the material layer is improved. In the mixing process, water is sprayed or steam is introduced, so that granulation is promoted, the temperature of the material is raised to be above the dew point, and the air permeability of the material layer is prevented from being reduced due to moisture condensation in the subsequent sintering.
