Abstract By the experiments of shaking table，investigations of the fluidization of iron concentrate ore in bulk under dynamic loading have been launched. With the use of digital image capture and processing technology，the law of fluidization evolution is revealed；and the effects of different influencing factors are analyzed，such as moisture content，acceleration，dense degree. The results show that the fluidization of iron concentrate ore is mostly influenced by moisture content，which exists a critical value；and it hardly affected by acceleration when moisture content below 8%. At the same time，it can be postponed but cannot be blocked by the increase of dense degree. The article also gives some suggestion about safety margin of iron concentrate ore?s moisture content and the measures on preventing the fluidization. The research has played a significant role in better understanding the fluidization of iron concentrate ore.
