On the capacity of continuous powder classification in a gas-fluidized bed with horizontal sieve-like baffles

Investigation of the particle flowpattern and segregation in tapered fluidized bed granulators

“…Literature provides several relations for quantifying the segregation (Rowe et al, 1972;Rowe and Nienow, 1975;Tanimoto et al, 1981;Bosma and Hoffmann, 2003). Tanimoto et al (1981) introduced the term "segregation distance"Ȳ s .…”

“…This is a measure of the amount of segregation of a given particle fraction in the bed caused by the passage of one fluidization bubble. Bosma and Hoffmann (2003) rearranged the original relation of Tanimoto et al:…”

Mixing and Segregation Characteristics of Binary Granular Material in Tapered Fluidized Bed: A CFD Study

“…Literature provides several relations for quantifying the segregation [13,[17][18][19]. Introduction of the term "segregation distance" Y s [18] and is the measure of the amount of segregation of a given particle fraction in the bed caused by the passage of one fluidization bubble.…”

Screening of Colloids by Semicontinuous Centrifugation

“…With laboratory devices a solid mass of a few grams can be classified while in the pilot and industrial scale the solids throughput is between a few kilograms per hour and hundreds of tons per hour. For industrial particle screening in the gas phase, cyclones, risers, centrifugal classifiers [14], fluidized beds [15] and sieving techniques are used to separate particles above one micron [16]. For smaller particles only laboratory and analytical techniques are available to fractionate them.…”
