Introduction Lead and zinc are important industrial raw materials.The sintering process of lead and zinc production is a complicated chemo-physical process, which involves physical and chemical changes such as evaporation and condensation of water, decomposition of solid materials, oxidation-reduction reactions, solid-state reaction and the melting and casting of chemicals.
When each material in sintering furnace charging has the lowest bulk specific gravity with a certain level of moisture, which enables the maximum capacity of the material, the best level of permeability will be reached, with the highest agglomeration[2,3]. 2.1 The important influence of permeability The permeability of sintering furnace charging is the volume of air moving per second per square meter of grate area on the updraft sintering bellow, or the speed of air (m/s).
