Influence factors of the viscosity measurement of coal slurry for pipeline transportation
Tu Zhaomei
Abstract：In order to investigate the effect of measurement method,particle size distribution,mass concentration and temperature on the viscosity of coal slurry for pipeline transportation,coal slurry samples from Shaanxi Shennan mining area were systematically studied.Resuits show that the viscosity measured using rotary viscometer is 30％ higher than that measured by capillary viscometer.The apparent viscosity increases with increase of proportion of Ⅳ-grain size range and mass concentration,while decreases with increase of temperature.The viscosity measurement concerning on the piping transportation of coal slurry should comprehensively consider the impacts from the measurement method,particle size distribution,mass concentration and temperature.
