  • Introduction to Iron ore Pellets and Pelletizing processes

    23/02/2013· 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 (0.074 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.

  • Iron Ore Pellets and Pelletization Process IspatGuru

    26/11/2014· Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is

  • Drying of Iron Ore Pellets Analysis with CFD

    The average diameter for iron ore pellets is about 12 mm and 99 % of all pellets have a diameter in the range 6.3 -16 mm and 70 % of these are, in their turn, within the interval 10-12.5 mm. Pellets can be indurated in shaft furnaces, in grate-kilns and on traveling grates. The principle of sintering pellets is almost the same in grate-kilns and

  • Iron ore pelletizing peter&x Outotec

    The on-size pellets are then fed to the induration machine. Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800-900 °C in a preheat zone, then finish the induration process at roughly 1200-1350 °C. The pellets are then cooled to a suitable temperature for transporting to a load out facility. Both processes recycle the heat from the pellet back through the process

  • Iron Ore Pelletizing Process: An Overview

    Pellets are obtained byadding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8]. This cohesive tension of fine particles due to water is called neutral tension. Neutral tension,

  • "Cold bonding of iron ore concentrate pellets" by Joseph A

    Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate-kiln furnaces. However, heat induration requires tremendous quantities of energy to produce high-quality pellets, and is consequently expensive. Cold bonding is a low-temperature alternative to heat induration. Pellets can be cold bonded using lime, cement, sponge iron powder, and

  • Pelletizing Wikipedia

    The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet properties. From an equipment point of view there are two alternatives for industrial

  • Pelletizing LKAB

    In the pelletizing plant, pellets are produced from the iron ore concentrate from the concentration plant. The pellets are dried, sintered and cooled before they are ready to be transported to the ports. 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

  • Iron ore pricing explained Metal Bulletin

    Different percentages of iron content reflect both the natural variation in iron ore grades found in mine deposits and the degree of processing (if any) employed to upgrade the ore for a certain use. In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required. For these reasons, the rule of thumb is “higher Fe grade,
