Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer than that used for sintered ore.
Jun 24, 2019· Learn about Outotec's Traveling Grate Pelletizing Plant the industry's leading induration technology for iron ore pellet production.
Introduction to Iron ore Pellets and Pelletizing processes Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh ( mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
Aug 04, 2015· The schematic figure of grate–kiln–cooler process for iron ore pellets is shown in Fig. 2. Processing of green pellets prepared from pelletizer is accomplished by three equipments: traveling grate (drying and preheating), rotary kiln (roasting) and circular cooler (cooling).
Two indurating furnace technologies dominate the pelletizing industry, the straight travelling grate and the graterotary kiln technologies. Although some of Metal 7's products could be adapted for the graterotary kiln operation, the company mainly focuses on the straight travelling grate applications.
Aug 13, 2014· Pellatization of Iron ores 1. PELLATIZATION OF IRON ORES Muhammed Labeeb 2. Engr 241 Pelletizing is the process of compressing or molding a material into the shape of a pellet Process objective is to transform fine iron ore concentrate into pellets suitable to feed Blast Furnace or Direct Reduction plant or COREX. Palletisation was invented to make use of Blue dust and ultra fine .
Straight Grate iron ore pelletizing system Introduction • Metso has built or participated in the building of 44 traveling grate pelletizing machines, having a production capacity of over 120 million metric tons per year. •Capacities ranging from million tons per year to million tons per year in a single system 25
Fig 7. Traveling grate pelletizing plant optimized by VNIIMT for iron ore pellets. Optimal control systems for gas supply from cooling one 2 to drying zone 1 (a) and from the roasting (Ro) and ecuperation (Re) zones to the heating zone (b . Fig 8. Traveling grate pelletizing .
There are two main processes for producing iron ore pellets: The GrateKiln system and the straight grate system. In the straight grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones. Any change in one section effects the residence time in another.
Kiln drive components Equipment description Grate The traveling grate is a conveyor that transports balled iron ore concentrate through crossflow processing zones. The conveying element is a continuous loop assembly of slotted ferrous stainless steel grate plates, chain castings, and side plates to carry a bed of agglomerates.
Straight Grate iron ore pelletizing system Principles of operation • In this process, the wet pellets are dried, preheated, indurated, and cooled on a continuous moving grate without intermediate transfers. •The process air introduced for pellet cooling is circulated from the cooling zone of the grate in a multipass manner to the other process
Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. Metso is the only supplier in the world that has both the Straight Grate and the Grate Kiln process for pelletizing.
