Fine Dry Grinding of Iron Ore for Pelletizing
When dry grinding is selected the moisture required for pelletizing must be provided either by wetting the ore and mixing prior to balling or by adding all the moisture in the balling device. To date only the balling disc has operated with a dry feed.
Introduction to 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.

Iron ore pelletizing systems - liming
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. liming is the only supplier in the world that has both the Straight Grate and the Grate Kiln process for pelletizing.
Iron Ore Processing for the Blast Furnace
blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").
Iron ore pelletizing Grate-KilnTM system
Iron ore pelletizing 3 Process flexibility There are two main processes for producing iron ore pellets: The Grate-Kiln system and the straight grate system. In the straight grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones. Any change in one section effects the residence
Iron Processing - FEECO International Inc.
Our heavy-duty iron ore balling drums are relied on by some of the industry’s top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.

Drying is a critical process step to achieve excellent pellet quality in pelletizing process. The complexity and energy consumption toward moisture removing, especially for highly hydrated iron ...
Iron ore pelletization - ScienceDirect
Figure 15.1 shows the flow sheets for modern straight grate and grate-kiln pelletizing processes. The straight grate process consists of a single furnace, which is divided into different zones for drying, preheating, and indurating green balls and zones for cooling the fired pellets.
The Iron Pelletizing Process: Part One :: Total Materia ...
The iron pelletizing process is often associated with low grade iron ore following a range of liberation techniques to prepare and make suitable for the blast furnace. In summary, pelletizing is achieved by combining the iron ore with water and a specific binder which is then rolled up in drum to produce relatively uniform pellets which can then be easily handled in downstream processes.
