Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers control over pellet size and produces a refined pellet product.PELLETIZING OF IRON ORE Due to its water absorption capacity and colloidal property, bentonite is used as a binding additive to convert iron ore fines into pellets Through this process, iron ore fines are converted into spherical pellets, suitable as feed material in blast furnaces for pig iron production, or in the production of direct reduction iron .

Iron Ore Pellets And Pelletizing Processes Vale

Iron Ore. and Pellets. Vale is the world’s biggest producer of iron ore and pellets, raw materials essential to the manufacture of steel. Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel.Iron-making processes such as the blast furnace or the DR-plant. Hence, an agglomeration technique should be applied to fine concentrate. The most commonly employed one is pelletizing in iron ore industry. In pelletizing, iron ore, water and a binder are balled in a mechanical disc or drum to produce agglomerates.

Iron Ore Pellets And Pelletization Process – Ispatguru

Bentonite for Iron-Ore Pelletizing. Bentonite is used as a binding agent in the production of iron ore pellets. Through this process, iron ore fines are converted into spherical pellets, suitable as feed material in blast furnaces for pig iron production, or in the production of.Composite agglomeration process (CAP) of iron ore fines has been proved an effective route for ironmaking burden production, and is characterized by low the fuel consumption and high the productivity compared with the traditional sintering process. Sintering behavior of pelletizing feed in CAP has not been studied fully yet.

Process Monitoring For Iron Ore Pelletizing – Xrd In

In general, three primary phases occur in iron ore pelletizing Mixing Preconditioning. The mixing step sets the stage for the remainder of the process, creating a homogeneous mixture that will allow for a uniform product to be created. In order to pelletize iron ore fines and or concentrate, a binder is needed.The iron ore pelletizing process consists of three main steps 1.
