The invention relates to an equipment to prepare ore concentrate for pelletizing and sintering/indurating of pellets in ferroalloys production. The equipment comprises a grinder ( 1 ) arranged to grind the concentrate to a predetermined grain size. The equipment further comprises a drying apparatus ( 2, 3, 4 ) arranged to dry the concentrate before and/or during grinding by the grinder ( 1 ).

concentrate and bentonite pk mixer for irin ore pelletizing. 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 US3–5 million annually for bentonite.
The pelletizing tests conducted on four different iron ore concentrates were intended to provide a wider base for the comparison of the quality of pellets made with extracted peat moss and the conventional method of using bentonite as a binder. The generation of the relevant data for these comparisons was planned in two stages, as follows:
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.
6 Iron ore pelletizing Grate The traveling grate is a conveyor that transports balled iron ore concentrate through crossflow processing zones. The conveying element is a continuous loop assembly of slotted ferrous stainless steel grate plates, chain castings, and side plates to carry a Equipment description bed of agglomerates ...
