The purpose of this paper is to provide details on the performance of the full-scale RC in the gravity separation of a coal and mineral matter feed in the size range of 0.25–2.0 mm. Historically, this feed has been processed using spirals, however, there is a strong trend now in Australia to employ fluidized bed devices, thus allowing significant changes to be made to the cut-point.

A laboratory scale reflux classifier with three distinct inclined sections (70° from the horizontal), consisting of 6, 8, 12 channels with perpendicular channel spacings of 6.50, 4.50 and 2.10 mm respectively was built and commissioned at UKZN.
The performance of the full-scale RC is described in terms of the partition curves for individual size fractions, and in terms of the yield–ash condition on the feed washability curve. It is concluded that the separation performance is equivalent to that obtained at the pilot scale.

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 ...
Abstract The Ludowici LMPE Reflux Classifier is a new device designed for classifying and separating particles on the basis of size or density. This work presents a series of experimental results obtained from the first pilot scale study of the reflux classifier (RC). The main focus of the investigation was to assess the particle gravity separation and throughput performance of the device.
