Abstract The Reflux Classifier is an innovative device offering advantages in both particle size classification and gravity separation. The system is a combination of a conventional fluidised bed and sets of parallel inclined plates as used to achieve a high throughput in a lamella settler. A reflux action develops as a result of fluidised particles segregating onto the inclined plates, and ...

WO2000045959A1 - A reflux classifier - Google Patents
A reflux classifier for segregating particles by size or density uses a fluidized bed in a chamber (10). Arrays of inclined plates (14A, 14B and 14C) forming lamellae (12A, 12B and 12C) divide the chamber into zones into which particles of predetermined size or density migrate. Particle differentiation is controlled by plate length, inclination and spacing in each array, combined with ...
