agglomeration technique is pelletizing by which a mixture of iron ore, water, and binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets) (Sivrikaya and Arol, 2010). A narrow size distribution in green pellets is an important criterion for the pellet

Table of ContentsDesign Considerations for Selecting a Grinding SystemOpen vs. Closed Circuit Dry GrindingEffect on Pellet QualityOperating Considerations Screening during the production of high-grade lump ore for blast furnace burden, particularly from recently developed ore deposits in Australia, South America, and Africa, has resulted in large tonnages of fine iron ore.

The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet properties.

If the ore is a Hematite ore, coke or anthracite coal can be added to the mix to work as an internal fuel to help fire the pellets. This mixture is blended together in a mixer and fed to balling discs or drums to produce green pellets of size typically about 9-16mm. The green pellets are then fed to .

The powdery iron ore concentrate is mixed with a small amount of bentonite clay binder and then rolled into marble-sized pellets in balling drums. The image below shows the inside of a balling drum, with thousands of round pellets within. Source: Photograph by Randy Schaetzl, Professor of Geography - Michigan State University

Jan 01, 2012· 1.1.3.2.2.2 Green Pellets. The ore is crushed, ground, and concentrated in several steps to very small grain size—e.g., over 75% less than 45 μm. Binder (bentonite or organic) and possible additives are fed in the slurry and mixed before filtering. The filter cake is transported to large balling drums or balling discs to be rolled to green ...

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.

The iron ore and additives with given moisture content are pelletized (formed into small balls referred to as green balls or green pellets) in a balling device. This could be a balling drum or a balling disk Pellets of various sizes exiting the balling device are discharged afterward on a deck of rollers, the roller screen, for removal of the ...

Green ball preparation De-watered or re-wetted pellet feed is mixed with additives and then processed in the (green) ball preparation plant. This is typically equipped with 4 to 6 balling circuits consisting of a feed bin, balling drum, roller screens and conveyors for circulating the materials. The balling drum is inclined 6 to 8° to the

chrome ore, iron ore, manganese ore or niobium ore as well as for steel plant residues. Steel belt plants differ from traveling grate plants in terms of the lighter design of their indurating machines and process gas systems. Green pellets are transported through the indurating machine by a perforated steel belt instead of pellet cars, while ...
