The median agglomerated number was initially increased as the agglomeration progressed and asymptotically approached a constant …
Why Agglomerate Powder?
When powder is agglomerated, however, particularly by wet granulation (also known as tumble-growth or agitation agglomeration), flowability is greatly improved. Greater flowability lends several advantages to any production setting, including a more consistent product, higher process efficiency, reduced downtime, and more.
Iron Ore Sintering: Raw Materials and Granulation
ABSTRACT Sintering is an agglomeration process that fuses iron ore fines, fluxes, recycled products, slag-forming elements and coke. The purpose of sintering is to obtain a product with suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is widely studied and researched in the iron …

Agglomeration of iron-BEARING fines: selection of the …
In the production of hot briquetted iron some fine by-product is generated. This material consists mainly of metallic iron and iron oxides. Before utilization of these fines in the steel mill and/or direct reduction plant, agglomeration is required. To get briquettes with sufficient strength a binder has to be added to the fines. In this study, the various …
