PROCESS FOR THE OPTIMIZED PRODUCTION OF IRON ORE PELLETS |
摘要 |
The present invention describes an advantageous and effective streamlined process for the production of iron ore pellets, the green pellets replacing the burnt pellets for covering the metallic surface in “travelling grate” furnace during the burning step, the process comprising at least some or all of the steps of grinding the iron ore; filtering the crushed iron ore; mixing the filtered iron ore with at least one binder; pelletizing the mixture; drying the green pellets; transferring the pellets to the side and bottom grids of a “travelling grate” furnace equipment and screening the burnt iron ore pellets. An optimized process for the production of iron ore pellets is provided that is innovative, efficient and economical when compared to currently known processes. |
