Iron Ore Pellets Screening Solutions The size distribution of iron ore pellets is among the most important quality parameters for the end users of those pellets, the steel mills. The tighter the distribution is, the better the performance and energy efficient the steel making process will be.
Pelletizing iron ore The equipment used to pelletize iron ore needs to be capable of conveying, feeding, mixing and screening a wide range of materials under the toughest conditions. High handling speeds and high plant availability are both essential. Here, Schenck Process solutions make a vital contribution to ensuring consistent quality and optimizing the production process.
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. Discs usually do not have a separate screening circuit at the disc. Green pellets are then transported to the induration process. Pellets
Iron Ore Pelletizing Induration Equipment In the indurating zone, pellets are brought up to final indurating temps. Hot gas recycled from the cooling zone is further heated up to 1200-1340 °C through a
The iron ore and binder mixture enters the high end and finished pellets exit the low end. A roller screen is usually attached to the exit to separate pellets within the desired range from undersize and oversize, the latter two streams being recirculated (oversize after being crushed).

Pellet hardening (indurating) Hearth layer and product screening ; In order to adjust the moisture content, water is added in the mixing step. The ore is then mixed with small amounts of binding agents. Fluxes such as limestone, olivine, and dolomite give the pellets the necessary physical and metallurgical properties for further processing.
Iron Ore Pellets. The Process Development Behind Iron Ore Pelletizing . As there can be significant variation in process requirements and sources of iron ore fines, testing is often an essential part of the development of a successful iron ore pelletizing operation.
Some iron ore companies are already marketing ‘green’ iron ore pellets, while others are only just starting to develop beneficiation processes for their production sites. For a high-grade iron ore deposit (ie greater than 62 per cent), a dry crushing and sizing process is sufficient to achieve the required product quality and size fraction
Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter
Cliffs is shortly starting to produce DR-grade iron ore pellets in volumes to prepare for its new HBI plant operations in early 2020, Goncalves said. "We are a year away from starting to supply HBI to the market. In July we will start producing 3.5 million lt/year of DR-grade pellets out of Northshore," he said.
Pellets are small balls of iron ore used in the production of steel. They are made with technology that uses the powder that is generated during the ore extraction process, once considered waste. The pellets are used in the production of steel which is used in the construction of bridges, cars, planes, bicycles, household appliances and much more.

Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.
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].
