Iron ore green balls are soft and easy to break. So after the pelletizing and screening operations, iron ore pellets have to be hardened in a furnace through a firing process. Once fired, they can be handled, loaded in ships or trains and delivered to the end users.
#0183;#32;The ratio in the output from the three main pelletizing technologies changes depending on practical circumstances, such as iron ore reserves, iron ore types, market demand, and required investment. The ratio for gratekiln pellets has increased to % in 2011 from % in 2000, while the ratio for shaft furnace pellets has dropped to % in 2011 from % in 2000 in China (see Figure
#0183;#32;We conclude that gratekilncooler systems provide superior pellet quality, The use of binders for iron ore pelletizing is required to: (a) fire clay, fuller''s earth, and kaolin.

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.

The premier, proven burner for iron ore sintering and pelletizing plants using straight/traveling grate kilns. IJet can also be used in a number of other applications such as hot gas generators, calciners and preheat chambers.
global website Products Pyro processing systems Iron ore pelletizing systems Grate kiln systems Grate kiln systems. Grate Kiln Systems typically consist of the Grate section, the Kiln Section, and the Cooler section. The three combined sections allow for the drying, preheating
LKAB has six pelletizing plants: three in Kiruna, two in Malmberget and one in Svappavaara. The total capacity of the plants amounts to approximately 28 million tonnes of processed iron ore products per year. The pellets are formed. In the pelletizing plant, a clay mineral, bentonite, is added as a binder in the iron ore concentrate.
Plant overview GrateKilnTM iron ore pelletizing system The first GrateKilnTM system pellet plant was installed in 1960. The plant took iron ore concentrate and produced superior iron ore pellets (which are spheres of high iron content and uniform quality) for blast furnace and direct reduced iron feed.
anticipates continued growth in this market as more beneficiation and pelletizing plants are needed to maximize the output from lower grade ore bodies. currently offers the Grate Kiln Iron Ore Pelletizing system. With the purchase of the Straight Grate Technology from Jacobs, will be able to offer both systems.
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

Outotec''s traveling grate pelletizing plant is the industry''s leading induration technology for iron ore pellet production for a wide range of plant capacities. Based on over 60 years'' experience and worldclass Ramp;D, our process produces uniform pellets and ensures high performance and quality, with low investment and operating costs, as well as decreased energy consumption and emissions.
The first GrateKiln System pellet plant was installed in 1960. The plant took iron ore concentrate and produced superior iron ore pellets for blast furnace and direct reduced iron feed. Since then, GrateKiln Systems have been used for over 50 plants, on both magnetite and hematite ores, with an installed capacity of over 115 million tpy. TM
capacity for producing more iron ore products, an extensive program of estment is being implemented, amounting approximately11 billion SEK. The program includes new pelletizing and concentrating plants in Malmberget and Kiruna, increased capacity in the Kiruna mine and investment in a new ore harbor in Narvik, as well as investments in Logistics.
