In most cases the REFLUX™ Classifier achieved Ep values less than 0.05 for size fractions larger than 1.0 mm. Based on these limited sets of results, the REFLUX™ Classifier does appear to suffer from more drift in density cut point than DMCs, but the drift was still relatively minor.

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.

The Reflux Classifier (RC) is a relatively new technology for the coal industry. The potential of this equipment for the treatment of iron ore was demonstrated in this paper, especially for the size range between 150 μm and 45 μm. The performances of the RC out of this size range need to be more specifically assessed.
