Study on resistance loss characteristics of iron concentrate pipeline transportation

Resistance loss is one of the main parameters in the designing of slurry pipeline transportation, how to predict calculation accurately is an extremely important job. In this paper, aiming at long-distance characteristics of iron concentrate slurry pipeline transportation, a new model based on the modified parameters of Fei Xiangjun resistance loss model and Durand resistance loss model was put forward, the modified model made a comparative analysis between data measured at the scene and results calculated in two models mentioned above. The results show that the calculation results of the resistance loss using modified Fei Xiangjun are more accurate in the real operation condition. Therefore, slurry flow rate and the concentration are both factors that would affect the pipe resistance loss were deeply discussed, which can give a reference in the designing of pipeline transportation.
