Balling drums . The balling area is where the powdered ore is mixed with water and rolled in rotating drums to create spherical balls. The green balls are spherical agglomerates nominally mm in diameter, formed by rolling a moist mixture of finely ground iron ore concentrate, binder and sometimes a
#0183;#32;1. Introduction. Iron ore pelletization plants in the United States used approximately 612,000 metric tons of bentonite as a binder to produce iron ore concentrate pellets in 2000 (Virta, 2001).It is a major cost item, with individual plants spending US35 million annually for bentonite.
Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. 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.
#0183;#32;The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process
The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing Pelletizing A pellet plant contains a series of balling drums where the iron ore. Balling Drum for Pelletizing of Iron Ores Kurt Meyer. /5() balling disc in pelletization of iron ore process. Iron ore
FLOFORM Iron Ore Pelletization FLOFORM, an alternative Traditionally bentonite is used as binder, but it reintroduces deleterious elements such as silica and alumina. FLOFORM is typically dosed at % prior to balling, about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
#0183;#32;The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization:
materials, balling, and firing for iron ore pellet production. Specification requirements of pellet feed Raw material characteristics are critical for the pelletizing process.
Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter
Iron Ore Pelletization Technology Need. Pellets form one of the best options of agglomeration of fines, due to their, green ball formation is similar to snowball growth by layering 14 Water Particle Green Ball Formation a balling drum,

Pelletizing, or balling, carried out through either a disc pelletizer or rotary drum, is a key part of efficiently and sustainably producing steel from iron ore fines of varying sources. FEECO is a leader in feasibility testing, custom disc pelletizers and balling drums, and aftermarket services for the iron ore balling/pelletizing industry.
Balling Disc In Pelletization Of Iron Ore Process XSM Disc Pelletizer The formation of raw iron ore pellets also known as pelletizing has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference transport and use.

Iron ore pellets are spheres of typically 616 mm ( in) to be used as raw material for blast typically contain 6472% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.
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 1/4quot; and 1/2quot;).
