【 摘 要 】

References(20)Cited-By(10)The centrifugal sedimentation of concentrated slurry was analysed with due consideration of concentration transition in the suspension, rising rate and internal compressible behaviour of the sediment. In accordance with this analysis, it was shown that the centrifugal sedimentation process could be predicted only from the experimental data of compression and gravitational settling velocity.The theoretically calculated centrifugal settling processes for yeast-, limestone- and Hara Gairome clay-water slurries were favourably coincident with the experimental settling processes under conditions in which the centrifugal effect ranges from 30 to 400. Also, a convenient method was proposed to predict the compression behaviour of the sediment at low compressive pressure from the centrifugal settling data.
