Jan 01, 2015 Cold bonding is a low-temperature alternative to heat induration. Pellets can be cold bonded using lime, cement, sponge iron powder, and organic materials such as starch and flour. Cold bonding consumes less energy than heat induration, and has found favor for bonding self-reducing pellets and for refractory ores that are difficult to heat-treat

Instead, it was the development of iron ore pellets, which today account for more than 80% of the iron ore fed to American blast furnaces. Most hematite (a form of rich iron ore) still used, whether foreign or domestic, is also enriched and agglomerated into various forms similar to taconite pellets

Nov 01, 2006 The cold-bond agglomeration process is increasingly being used as a means of recycling iron-rich steel plum byproducts back to the blast furnace. Even though an increasing number of plants are adopting this process, the use of cold-bonded agglomerates as burden material for the blast furnace is restricted to about 5% of the total burden material. This is because the cold-bonded agglomerates

Palletizing - A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2"). Pellets are screened to meet the size specification, with undersized or oversized pellets crushed and returned to the balling drums
