iron ore pellet fines generation handling

Transporting, handling and storing behaviour of iron ore

The presence of fines can significantly affect the behaviour of iron ore pellets during these processes. In addition, increased volumes of sinter fines are being produced and handled and their behaviour can also be significantly affected. Silos and other equipment handling the fines can experience such phenomena as caking, arching and alteration of flow pattern, leading to operational

Surface breakage of fired iron ore pellets by impact

15/01/2019· Fines generation during handling of iron ore pellets can have two implications: economic and environmental. From the economic standpoint, fines generation due to surface breakage or attrition may lead to losses, since they will be removed from the feed of direct reduction furnaces by screening, in order to avoid loss of furnace permeability and generation of clusters, which disturb the flow of

Direct Reduced Iron (DRI) Cargo Handbook the world's

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ore in solid form by reducing gases is called

Maximizing Iron Unit Yield from Ore to Liquid Steel (Part

Low tumble and cold compression strengths mean higher fines generation during handling. Bulk Density Low bulk density means a reduction in unit weight or capacity of a hopper or other volumetric devices, such as the reduction furnace. Pellets and lump ores should have a bulk density of at least 2.2 t/m3. REDUCTION CHARACTERISTICS. Reducibility can be gauged by the residence time in the

01/05/2014· Thus, dust generation from shipping and handling pellets will depend on the quantity of pellets handled and how much they are handled. These results also showed that the type of industrial furnace used to harden iron ore concentrate pellets may affect their fines generation and potential dustiness. Iron ore concentrate pellets have the potential to fracture and abrade during transportation

Iron Ore Pellet an overview ScienceDirect Topics

Available sources of iron oxide include high-grade lump ore, beneficiated iron ore fines, iron ore pellets, and agglomerates from dusts produced by the BF, basic oxygen furnace, and the EAF. Most DRI is produced in shaft furnaces, which require a uniform-sized coarse feed. Due to the high gas velocities and abrasive conditions in shaft furnaces, fine particles are not suitable as charge
