Iron ore pelletizing systems - Iron ore agglomeration is a wet agglomeration process and moist green-balls are subsequently dried and heat hardened at high temperatures to make pellets the presence of binders affects the entire process from green-ball formation to pellet hardening
Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.
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 ...
Iron ore pelletizing, or balling, is the process of transforming fines into spherical granules anywhere from 8 – 16mm in size via tumble-growth (agitation) agglomeration using either a disc pelletizer (pan granulator) or rotary drum.
Iron ore is found in nature in the form of rocks, mixed with other elements. By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel companies. The iron ore produced by Vale can be found in houses, cars and appliances.
When applying the results in balling of iron ore, the differences in agglomeration conditions should be recognized. Industrial iron ore green pellets are over-saturated and a supporting network of viscous liquid is formed on the green-pellet surface . The strength of this network is initially controlled by the viscosity of the liquid phase.
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 grate-kiln pellets has increased to 55.33% in 2011 from 7.21% in 2000, while the ratio for shaft furnace pellets has dropped to 42.05% ...
The disk pelletizers are used for the agglomeration of powdery primary and secondary materials such as filter dust. The primary area of application is the agglomeration of iron ore concentrate to form pellets with a target size of 9 to 16 mm. Inside the inclined cylindrical rotating container, a powdery input material is formed with or without the addition of an evaporated liquid binding agent.
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. is the only supplier in the world that has both the Straight Grate and the Grate Kiln process for pelletizing.

Prior to the application of pelletizing discs for agglomeration, it is always necessary to assess the basic pelletizability of the different materials as well as to obtain data for the machine and process design on the basis of empirical testing on laboratory or pilot-plant scale to enable reliable parameterization of the pelletizing process.
12/28/2015· Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson (Yamaguchi et al., 2010). The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, Michigan in ...
