In an iron ore pelletization process in which particulate ore is mixed with particulate polymeric binder in the presence of moisture and the mixture is pelletised, the particulate binder is a blend of ionic synthetic water soluble polymer, such as a copolymer of acrylamide and sodium acrylate having intrinsic viscosity 2 to 16 dl/g, with a larger amount of a guar gum.
Jan 01, 2012· In Grate-Kiln process, green pellets are fed on oil or gas-fired endless Straight Grate machine where they are dried and preheated. The preheated pellets are then fed to a rotary kiln where their temperature is raised in oxidizing atmosphere to 1290–1400 °C. In induration, ore grains are sintered together with oxidation and slag-forming bonds.
Iron ore must be shipped in bulk for maximum economy. 1.2 Pretreatment process In this process, the iron ore is ground into fines having qualities required for the subsequent balling process.

In pelletizing, a mixture of iron ore, water and binder is rolled in a mechanical disc or drum to produce agglomerates (green balls or wet pellets). Green pellets then undergo a thermal process, which consists of three stages, namely drying (250 -400 o C), preheating (900 -1100 o C) and firing (1200 -1300 o C).
