· 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. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through ...
The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifiions, dosed, and mixed together to feed the pelletizing process; 2. Ballingprocess ...

Iron ore sintering creates substantial offgas volumes, and treating these in order to meet increasingly stringent environmental standards is expensive. EOS® uses recycling technology to reduce offgas volumes by 40 to 50 %, resulting in smaller secondary gas treatment systems. This means: • Lower capital investment • Reduced operating costs Conventional sintering uses ambient air to ...
· Pelletizing differs from sintering in that a green unbaked pellet or ball is formed and then hardened by heating. Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making ...

Sinter mix gaspermeability declines with increase of its iron ore concentrate content, reducing throughput rate of sintering machines. The authors propose to solve this problem by means of using the Yakovlevskoye deposit sintering ore. It is only slightly inferior to iron ore concentrates with regard to iron content, but increases gaspermeability of sinter mixes by the factor of 2ndash;4.
