Pelletizing Wikipedia

Pelletizing Wikipedia

Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and process is considered an excellent option for the storage and transport of said materials. The technology is widely used in the powder metallurgy engineering ...

Effect of Iron Ore Pellet Size on Metallurgical Properties MDPI

Effect of Iron Ore Pellet Size on Metallurgical Properties MDPI

Iron ore pellets are small and hard spherical particles agglomerated from a fine iron ore concentrate. They are used in the blast furnace process to produce hot metal. The diameter of blast furnace pellets is usually between 8 and 16 mm. In this study, a batch of magnesia iron ore pellets was first sieved into particle sizes of 810 mm, mm, mm and 1620 mm, and the four ...

Decreasing bentonite dosage during iron ore pelletising

Decreasing bentonite dosage during iron ore pelletising

Abstract Factors affecting the bonding efficiency of bentonite during pelletising were investigated. Results show that it is influenced by the properties of bentonite, water and iron ore concentrate. The dosage of bentonite can be halved by exchanging cations in the interlayer to activate bentonite, removing bivalent cations to soften the water and milling the mixture to advance the contact ...

Iron Ore Pellets and Pelletization Process IspatGuru

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 transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

Applications of Iron Ore Pellets Iron ore Pelletization Process

Usually, Iron Ore is manufactured and converted into Pellets. These are oval lumps of iron ore that are hardened using fuel. This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum ...

Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800900 °C in a preheat zone, then finish the induration process at roughly °C. The pellets are then cooled to a suitable temperature for transporting to a load out facility.
