Abstract Nowadays，in order to achieve the goal of zero-waste in the steel industry，sintering dust and blast furnace dust are recognized as two kinds of significant secondary resources. Owe to the fact that the dusts have undergone some extent of high temperature processing，their particles have perfect crystalline and low surface activity. Under air and deionized water milling condition，the planetary milling activation mechanism of sintering dust and blast furnace dust were investigated by using granulometry analysis，X-ray diffraction (XRD)，scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The results show that along with the milling progresses，the mean particle size and the crystallite lattice size decrease gradually. Meanwhile，the hematite phase diffraction peaks continuously broaden，the lattice distortion，the dislocation density，the factional amorphization and stored energy increase gradually. For sintering dust，the effect of wet grinding is superior. For blast furnace dust，the effect of dry grinding is superior. The particles of activated sintering dust are more likely to reunion together than activated blast furnace dust. After half an hour’s planetary wet milling，the mean particle size of activated sintering dust decreases to 3.3 μm， the corresponding crystallite lattice size decreases by 40%，the dislocation density and the factional amorphization are 4.8×1014 m/m3 and 21.3%， and the total stored energy is 126 kJ/mol. After half an hour，s planetary dry milling，the mean particle size of activated blast furnace dust decreases to 4.1 μm，the crystallite lattice size decreases by 28%；the dislocation density and the factional amorphization are 9.8×1014 m/m3 and 14.8% and the total stored energy is 229 kJ/mol.
