Experiment research and mechanism analysis on rheological properties of tailings slurry

The particle size and content of tailings are important parameters affecting the rheological properties slurry. To explore their influence law mechanism on properties, experiments slurry were designed carried out under different sizes conditions. quantified in paper. Bingham body model was used texperiment. “double 30” theory (“particle 30.0 μm” “content 30%“) proposed expounded. corresponding theoretical is established to analyze above results. conclusion as follows. agreeed models with content. behavior conforms Herschel-Bulkley for tailings, whose no larger than μm 30%. With increase fine its agrees better model. yield stress viscosity process transportation accordance laws theory. “Particle 30%” critical point characteristics tailings. Based obtained results, discuss mechanism. can provide guidance reducing pressure preventing pipeline wear cementation discharge an iron mine.
