Abstract
A reflux classifier for segregating particles by size or density using a fluidized bed in a chamber. Arrays of inclined plates form lamellae and 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 fluidization rate.
