The coke fine briquette machine is the key equipment in the production of coke briquette system, and the actual capacity of briquettes produced by the production line is determined by it. How to find the actual capacity of the coke briquette machine. Capacity=Pocket numbers*each briquette weight*RPM of the roll*6.
The present work describes the possibility of cold-briquetting of fine iron ore to produce DRI (Direct Reduced IRON) in several cost-effective ways using certain novel technologies developed during the last decade. Three possibilities of coal-based solid-state reduction of briquetted fine ore are discussed. The first one is still in laboratory ...

DRI fines, generated during its manufacture and handling, generate high content of fines in the size fraction less than 2 mm. It has iron content above 80%. It is difficult to directly use such iron-rich material in the primary steel making process, without agglomeration. At JSW Steel Vijayanagar, around 50 to 70 tons per day of DRI fines …
Conversion — Iron- and carbon-rich fines, dust and wet sludge converted to high-quality feedstock. Mixing — Connects fine carbon particles to iron oxides for improved reduction. Binder — Less binder for more high-value metallics and carbon recovery. Sizing — Our dies ensure precise sizing, from 10-150mm, for most smelting processes.
Now we have the "green briquette", which will revolutionize the steel production process," explains Marcello Spinelli, Executive Vice-President, Iron Ore. The production of "green briquette" will initially be carried out in pelletizing plants 1 and 2 at Tubarão Unit in Vitória (in Espírito Santo, Brazil), which are being converted ...

for the agglomeration of chromium ore fines. They reported a sinter yield of up to 70.6%, a tumbler index of 57.27% of the produced sinter and the incipient formation of 20% mol-ten phase (olivine). However, as discussed previously, the briquetting of chro-mite ore fines requires costly binders, exhibits poor perfor-mance in the ferrochrome ...
In iron making process, sintering of iron ore fines is an integral step to utilize not only the ore fines but also to introduce a part of flux (limestone and dolomite) along with the sinter in blast furnace burden. ... The same is also applicable to Ferro-chrome and Ferro-manganese industries. A 4 m 2 area circular (2.25 m diameter) pan with ...
The ratio of these components in the briquette charge depends on the type of imported ore fines. At 30% of the dust content in the mass of the briquette, only 1.5% of the cement by mass of the briquette is required. The share of cement increases to 3% at 15% of the content in the dust in the briquette. Fig. 3.82.
After heated in the microwave field of 10 kW, the temperature of 1 kg carbon-containing chromite ore fines rose up to 1 100 °C in 7 min, at a temperature rise rate of 157. 1 (°C · min −1 · kg −1), whereas the temperature of 1 kg carbon-containing magnetite ore fines rose only up to 1 000 °C in 10 min, at a temperature rise rate of 100 ...
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 ...

To characterize the briquette quality the following parameters were determined: The compressive strength σ P (based on former TGL 9491) of the briquettes was tested with the universal testing machine UH-500kNA made by the Shimadzu Corporation. Pressure was applied by two compression pistons on the briquettes until the briquettes broke.
Hot sponge iron briquette, also known as HBI, is in the form of pellets, lumps, fines at a temperature of 650-700 Celsius is passed through hot roll briquetting machine where the product is pressed between the rolls at extremely high pressure to produce highly compacted pillow shaped material called hot briquetted iron.
