Exploring a new path of green and efficient utilization of sinter
Efficient utilization of sinter return fine is an important measure to reduce cost, increase efficiency, save energy and reduce emission. A new path of green and efficient utilization of return fine was proposed to produce composite pellets. The metallurgical properties of composite pellets under the condition of hydrogen-rich blast furnace were studied. The …

Characterisation of binary mixtures of pellets and sinter for DEM
However, there are significant changes in the same when μ r (pellet-sinter) is varied from 0.01 to 0.1 (Fig. 8), just like in the case of calibration for sinter particles in Section 4.1. This proves that selection of contact parameters between individual materials is also important to represent mixtures of these materials.

used to manufacture pellets as a raw material for the blast furnace, was also adopted in this new process in order to agglomerate return fines of sinter in large quantities. How-ever, how to agglomerate return fines of sinter is a problem because the return fines are comparatively coarse and thus are difficult to agglomerate directly.

Influence of Proportion of Pellet on Burden Distribution
The angle of repose of sinter is 29°–33° and the pellet is 25°–26°. Therefore, the proportion of pellet will affect the angle of repose of ore and further affect the burden distribution . Using the upper limit of the angle of repose for sinter and pellet, the angle of repose of pellet is 0.7879 compared with the sinter.
