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. …
Furthermore, variables such as binder type, binder dose, compaction pressure, mixing, surface characteristics, and size distribution of raw material influence the final quality of the processed briquette . Nowadays, the iron ore pellet fines are used as a part of the sinter mixture during the sintering process to produce sinter for the blast ...

Maximum pressures of up to 3,900 kg/cm 2. The powerful axial piston pump of the hydraulic unit delivers an output of up to 37 kW. This allows the buildup of particularly high press pressures of up to 3,900 kg/cm2 (TH 800 M), resulting in extreme compaction of the briquettes produced.
Fines iron ore oxides are generated during mechanized mining as well as comminution, beneficiation, transportation, and agglomeration processes. These iron ore fines need to be taken care of and reused in ironmaking. The present work focuses on the utilization of those fines by agglomeration techniques and converting them into reduced …

Hot briquetting is applied both for products from pellets and lump ore (shaft furnaces) and from fine ore (fluid bed reactors).
As the supply of lump ore fell, the first pelletizing plants were set up in Brazil, allowing the use of fine ore (pellet feed). ... 2023, when the company's president, Eduardo Bartolomeo, symbolically started up the …
The production rate of sinter strand and indurating machine comprises 1500–10000 and 2500–9000 ton/day, respectively. ... (every 1% decrease in the content of a 5–0 mm fine fraction in an iron ore charge will lead to a decrease in coke consumption and an increase in ... The maximum achieved value of the briquette proportion in the …
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 …
