This work proposes a novel horizontal high-shear granulator for iron ore granulation before sintering process. The granulation behavior such as growth process and structure of granules were firstly analyzed, followed by the effects of operation conditions such as water content, initial particle size distribution, and the concentrate ratio. The …
