The schematic represents the HBI briquetting process. Direct Reduced Iron is discharged hot from the reduction furnace and screw fed into the nip between two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures and high pressing forces.
Hot briquetting is a reliable, fully developed industrial concept for the passivation of direct reduced iron produced with the various processes of direct reduction. Because, during hot briquetting, the large specific surface area of direct reduced iron is drastically reduced, the well known problems caused by reoxidation, overheating are avoided.
Briquetting and nodulizing are cold binding processes and mostly used for the recycling of recovered iron ore wastes in the steel plant. Sintering and pelletizing are the processes of major importance for the iron production.
RECYRON® is a highly flexible process to utilize fine ore as well as all possible iron ore and carbon containing wastes to produce DRI. A comparative description of these three processes...

High pressure dry powder briquette machine can make briquettes from a wide range of powdery materials, including carbamide, pigment, calces, plastic, chemical fertilizer, cryolite, coal, coke powder, clay, caustic soda , alumina, active charcoal powder, ore dust, iron ore, magnesium powder, aluminum powder and many other mineral powder materials.
The agglomeration process in which lumps are made by compacting the iron bearing fines and dust with addition of binder and also de airing these mixtures inside the vacuum chamber of the briquetting machine. So, briquetting process is developed to meet these demands. This process aims at recycle and reuse of the low grade iron ore and plant fines.
The below image shows the hot briquetting process of HBI production. In first step of the HBI production process, the DRI is released hot from the reduction process. The hot feed thrust into the nip in the middle of the two counterrotating rollers.

Iron briquetting increases the value of the loose bits of cast iron, as briquettes create an optimal charge in blast furnaces, where the iron is smelted and returned to useful production. Iron briquettes command a higher price at foundries than loose iron chips, as they yield metal in the smelting process.
