| Abstract: | In view of the sharp fluctuation in efficiency and economy of slurry transportation by pipeline,we analyze the ranges of particle size,transportation distance,pipe diameter,delivery concentration and the restriction of critical velocity and net positive suction head (NPSH),study the change laws of efficiency and economy of slurry transportation system caused by the change of transportation concentration,and propose the optimal construction method under specific working condition. |
