Sticking mechanism of low grade iron ore-coal composite in rotary kiln reduction

A rotary kiln (Φ1.5 m × 15 m) was designed to verify feasibility of the reduction technology of a low grade iron ore with low temperature via ore-coal composites. One of the troublesome problems was the sticking of kiln burden during the reduction process. Reduction behavior and sticking mechanism o...
