  • Iron ore pelletizing

    Our systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. Also during the processing of high grade iron ores which don't need beneficiated, fines which are generated can be pelletized and used instead of being disposed of.
