Iron Ore Pelletizing Plant Costs

The aim of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed. The transformation is achieved by the traveling grate and kiln.

The traveling grate transports the pelletized concentrate through a series of controlled temperature zones to produce a preheated pellet of 800-900буC, which is dropped into the rotary kiln.

The indurated pellets are now dropped into an annular cooler where the pellets are cooled to a suitable temperature for transporting on a belt to load out facilities. The gases from the cooler are recycled to the kiln and the grate, resulting in the Grate-Kiln being the most energy efficient system for producing indurated pellets.

Iron Ore Pelletizing Plant

The iron ore plant contains different pieces of equipment. The major process in iron ore pelletizing operation are the concentrator, balling, induration and handling. The pellets at this stage are becoming stable and can be dropped into the kiln without braking. The kiln is applied to drive heat into the pellets to force the reaction throughout the pellet. In an effort to recoup all the heat that is currently in the pellet after the kiln, the pellets fall into a cooler. The Grate-Kiln System is basically a counter-flow heat exchanger; that is, the material moves in a direction opposite to that of the process gas flow. The iron ore pelletizing plant costs are different according to production requirements. If you are interested, please contact us for more information.
