May 10, 2014· In pelletisation, iron ore fines below 325 mesh are used for agglomeration. While sinters are porous and brittle, pellets are hard and compact. Hence pellets can …
In steel manufacturing industry, powdered iron ore is agglomerated in a pelletizing disk to form iron ore green pellets. The agglomeration process is usually monitored using a camera.
Agglomeration BENEFICIATION ... Pelletizing is the process through which ground iron ore fines are transformed into heat hardened spheres called "iron ore pellets". These pellets are suitable for use in an iron-making furnace such as a blast furnace or electric arc furnace. ... In its end product form, a typical iron ore pellet is roughly ...
2.1 Trends in the Seaborne Iron Ore Market The global seaborne iron ore market including sinter feed, lump ore, pellets and pellet feed has rapidly increased over the last decade. While sinter feed sales dominate the global seaborne trade, pellet feed and fired pellet sales have grown at a faster rate.
Iron Ore Pelletization is an agglomeration process of the disintegrated Iron Ore fines into Iron ore Pellet which is suitable for the utilization of downstream process of Iron Making. The GPIL Process is the Ore ground to the required fineness through wet grinding process mainly by Ball Mills and the slurry is dewatered by pressure filtration ...
agglomeration, are added into the iron ore fines to improve the pellet properties and impart strength to the pellets during wet, dried and indurated conditions [7 - 10, 19, 21]. Pelletization involves size enlargement of iron ore fines in presence of binders and moisture in critical amount by forming green
Our heavyduty iron ore balling drums are relied on by some of the industrys top producers to process iron ore fines into pellets for the steelmaking process.
