Nov 26, 2014· 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.
designs balling drums for the agglomeration of iron ore and other concentrates. Features 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 flux.

Iron ore pelletizing 3 Process flexibility There are two main processes for producing iron ore pellets: The GrateKiln 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
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
