احصل على السعرThe iron pelletizing process is often associated with low grade iron ore following a range of liberation techniques to prepare and make suitable for the blast furnace. In summary, pelletizing is achieved by combining the iron ore with water and a specific binder which is then rolled up in drum to produce relatively uniform pellets which can then be easily handled in downstream processes.
احصل على السعرIron Ore Pelletizing Aids Iron Ore pelletization is a tumble/growth agglomeration mechanism for solid particulates, which must comply with two key points. The first point is to reach, during the balling stage, the capillary state without exceeding it.
احصل على السعرIn 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 – 400oC), preheating (900 – 1100oC) and firing (1200 – 1300oC).
