process of sintering in agglomeration of iron ore

Numerical simulation model of the iron ore sintering process directly describing the agglomeration

Results show that both carbon content and melting temperature of the granule influence the final structure of the sintering bed. The obtained structural change of the sintering bed show that the proposed model is a potential tool to analyze the agglomeration phenomena occurring in the iron ore sintering process under various conditions.

Sintering plant at a glance

2014/10/2718 WHAT IS SINTER • Sintering is the process of agglomeration of iron ore fines into a porous mass by incipient fusion heat generated within the mass itself. 19. 19 TYPES OF SINTER • Depending upon weather bases have been incorporated in the Sinter mix, sinters are divided into three broad classes: - (i) Non Fluxed OR ACID SINTERS: - Those where no flux is

Iron Ore Pelletizing Essential in Meeting Future Steel Needs

Iron ore pelletizing, or balling, is the process of transforming fines into spherical granules anywhere from 8 – 16mm in size via tumble-growth (agitation) agglomeration using either a disc pelletizer (pan granulator) or rotary drum.

Iron Ore Agglomeration Technologies

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of highgrade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron
