The high-pressure briquetting machine comprises of two rollers that have synchronous rotation in opposite direction one is xed roller and the other is pressure roller. Material is fed from the top of the rollers by a force feeder with conical screw & continuously delivered into the middle of the rollers at high pressure. After the material forms into compact …
An alternative is hydrogen-based direct reduction using fine ore instead of pellets. Outotec's Circored technology is the only process for iron ore reduction based on hydrogen that has proven its functionality and performance in an industrial-scale demonstration plant. Circored technology is flexible in its production setup.
The briquetting process involves pressing the fines into a block or briquette of suitable size and shape in a briquetting machine, either with or without a binder. Previous work in CSIRO has shown that briquetting is a prospective alternative process …
Abstract The sinter–briquette complex firing process which is an effective technology for utilization of low grade ultra-fine ore is a method for charging sinter feed mixed with briquette made of ultra-fine ore. To uniformly fire briquettes using the excess heat from the lower part of the sinter feed bed, they must be segregated in that region. …
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 high-grade iron ore sources has …
The results confirmed earlier work that iron ore fines can be agglomerated by briquetting to produce a feed material suitable for a blast furnace. Feed moisture was found to be a …

Hot briquetting is applied both for products from pellets and lump ore (shaft furnaces) and from fine ore (fluid bed reactors).
This metal powder briquette machine can be used to compress iron ore fines, iron powder, mill scale, steel powder, ferrosilicon powder, etc. to form differently shaped briquettes that are rigid and unbreakable in the …
FeO ? 6 Fe. The compacted and sintered briquette of iron oxide is used in sponge iron manufacturing processes such as Midrex, HYL and SL/RN. A typical iron oxide briquette subjected to gas-based direct reduction is shown in Fig. 1. The as-reduced DRI briquettes are usually used as iron-bearing raw material for the manufacture of steel in pri-
