| Abstract: | The mechanism of highly viscous bauxite ores arch and blockage and the main factors influencing the flowability of ores in the silo were studied from mechanics theory,the indoor ore-drawing similarity simulation experiment and numerical analysis. It shows that the water content of ores,friction coefficient of the hopper wall and the loading ores amount are. the main factors influencing the flowability. A new flow-aiding technology was put forward according to the results of research. Through many field industrial tests, it shows the flow-aidiag technology can effectively solve the highly viscous bauxite ores problem of the arch and blockage in silo. |
