The most widely used industrial process for pellet induration is the grate-kiln process in China [[7], [8], [9]]. The iron ore is first crushed into a powder, mixed with additives and a binder, and rolled into green pellets (10–15 mm in diameter) that are sintered to pellets in a furnace during pelletizing of iron ore [10,11].The traveling grate indurating process is responsible for two-thirds of the world’s installed pelletizing capacity. TON Outotec offers the industry’s leading induration technology for iron ore pellet processing, which is based on over 60 years of experience and world-class R&D. This process produces pellets with excellent physicalNextGen Pelletizing™ TON

In the long-process of iron-making, the pelletizing process is a key step to turn iron ore into pellet (Guo et al. 2017, Purohit et al. 2018). Compared with sinter, pellet exhibits the advantage of lower pollutant and carbon emission. The emission intensities of SO 2, NO x, and CO 2 for pellet are 1/3 ~ 1/2 of those for sinter. Increasing theIron ore pelletizing is a two-step process. This begins with the formation of green pellets with the addition of a binder to improve agglomeration phenomena. Then it follows an induration process to obtain appropriate mechanical and Mechanism of magnetite iron ore concentrate morphology

Pelletizing, in ironmaking, is a process used to agglomerate iron ore concentrates with a granulometry <150 µm and low concentration of impurities.Iron ore concentrates are mixed with water, bentonite, and hydrated lime (cold agglomeration) and are treated in a rotary disk to form round agglomerates (green pellets) with sizes After the pelletizing process, the iron ore powder forms green pellets of uniform size. To facilitate transportation and processing, green and dry pellets must be of a certain strength. The important indicator used to evaluate the strength of green pellets is the green pellet drop number, which is generally required to be from 4–6 timesPolymers Free Full-Text A Review on the Effect of the

Effects of Pellet Basicity on the Simulated Deposit Formation
The pelletizing process’s energy consumption, CO 2 emission, and environmental pollution are much lower than the sintering process. In order to optimize the structure of the blast furnace burden and reduce the environmental pollution, (6) some companies have focused on the production of fluxed iron ore pellets to replace the iron ore sinterThe iron ore pelletizing process consists of three main steps: 1.

In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, can be recovered and incorporated into the pelletizing process to avoid wasting any iron-bearing material. The Pelletizing Process. The production of iron ore pellets from fines to finished product canThe pelletizing process, where the crude ore from the mine is upgraded, involves several steps, including grinding, balling, and induration; see Figure 1 to the left. In the grate-kiln induration process []—see Figure 1 to the right—the sintering is mainly taking place in a rotary kiln, where the pellets increase their strength and metallurgical properties.The Aerodynamics of an Iron Ore Pelletizing Rotary Kiln
