اقرأ المزيدThe 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 …
اقرأ المزيدThis research work focuses on the practicality of using organic binders for the briquetting of pellet fines. The developed briquettes were evaluated in terms of mechanical strength and reduction behavior with hydrogen. A hydraulic compression testing machine and thermogravimetric analysis were incorporated into this work to investigate …
اقرأ المزيدThe effects of the operating parameters of the briquetting machine, feed moisture content and the addition of hydrated lime as a flux on the green and fired properties of briquettes produced from Australian iron ore fines were investigated to determine the best operating conditions for producing satisfactory briquettes.
اقرأ المزيدAbstract 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.
اقرأ المزيدIn the agglomerated form, the iron fines with suitable organic or inorganic binder can be made briquettes, which can be added to the BOF as a coolant with much higher Fe recovery. The present study examines the feasibility of agglomerating the DRI fines to briquettes which can be directly used as coolant in primary steel making process.
