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.
The pelletizing process is a process which contains numerous sub-processes, or process segments. On the way from the mine to a final product, the iron ore goes through the following main process segments 1 The iron ore is crushed and the waste rock is removed. About 85 of the particles should be less than 44 m in length, width, or height.

Iron-making blast furnace requires high air permeability during operating so the iron ore fines should be processed into iron ore pellets in the iron ore pelletizing plant in advance. During the processing of high-grade iron ores which dont need beneficiation, many ore fines are generated which are usually regarded as waste.
Pelletizing is the process through which iron ore fines are transformed into an agglomerated form called iron ore pellets suitable for use in an iron-making furnace at a steel mill, such as a blast furnace or electric arc furnace. In its end product form, a typical iron ore pellet is roughly spherical in shape, measuring from 6 mm to 16 ...
